Making a drag-and-drop, multi-column responsive dashboard has never been easier. Has multiple bindings and works great with [Angular](https://angular.io/) (included), [React](https://reactjs.org/), [Vue](https://vuejs.org/), [Knockout.js](http://knockoutjs.com), [Ember](https://www.emberjs.com/) and others (see [frameworks](#specific-frameworks) section).

You can use the es5 files and polyfill (larger) for older browser instead. For example: ```html ``` ## Basic usage creating items dynamically... ```js // ...in your HTML
// ...in your script var grid = GridStack.init(); grid.addWidget({w: 2, content: 'item 1'}); ``` ... or creating from list ```js // using serialize data instead of .addWidget() const serializedData = [ {x: 0, y: 0, w: 2, h: 2}, {x: 2, y: 3, w: 3, content: 'item 2'}, {x: 1, y: 3} ]; grid.load(serializedData); ``` ... or DOM created items ```js // ...in your HTML
Item 1
Item 2 wider
// ...in your script GridStack.init(); ``` ...or see list of all [API and options](https://github.com/gridstack/gridstack.js/tree/master/doc) available. see [stackblitz sample](https://stackblitz.com/edit/gridstack-demo) as running example too. ## Requirements GridStack no longer requires external dependencies as of v1 (lodash was removed in v0.5 and jquery API in v1). v3 is a complete HTML5 re-write removing need for jquery. v6 is native mouse and touch event for mobile support, and no longer have jquery-ui version. All you need to include now is `gridstack-all.js` and `gridstack.min.css` (layouts are done using CSS column based %). ## Specific frameworks search for ['gridstack' under NPM](https://www.npmjs.com/search?q=gridstack&ranking=popularity) for latest, more to come... - **Angular**: we ship out of the box an Angular wrapper - see Angular Component. - **Angular9**: [lb-gridstack](https://github.com/pfms84/lb-gridstack) Note: very old v0.3 gridstack instance so recommend for **concept ONLY if you wish to use directive instead**. Code has **not been vented** at as I use components. - **AngularJS**: [gridstack-angular](https://github.com/kdietrich/gridstack-angular) - **Ember**: [ember-gridstack](https://github.com/yahoo/ember-gridstack) - **knockout**: see [demo](https://gridstackjs.com/demo/knockout.html) using component, but check [custom bindings ticket](https://github.com/gridstack/gridstack.js/issues/465) which is likely better approach. - **Rails**: [gridstack-js-rails](https://github.com/randoum/gridstack-js-rails) - **React**: work in progress to have wrapper code: see React Component. But also see [demo](https://gridstackjs.com/demo/react.html) with [src](https://github.com/gridstack/gridstack.js/tree/master/demo/react.html), or [react-gridstack-example](https://github.com/Inder2108/react-gridstack-example/tree/master/src/App.js), or read on what [hooks to use](https://github.com/gridstack/gridstack.js/issues/735#issuecomment-329888796) - **Vue**: see [demo](https://gridstackjs.com/demo/vue3js.html) with [v3 src](https://github.com/gridstack/gridstack.js/tree/master/demo/vue3js.html) or [v2 src](https://github.com/gridstack/gridstack.js/tree/master/demo/vue2js.html) - **Aurelia**: [aurelia-gridstack](https://github.com/aurelia-ui-toolkits/aurelia-gridstack), see [demo](https://aurelia-ui-toolkits.github.io/aurelia-gridstack/) ## Extend Library You can easily extend or patch gridstack with code like this: ```js // extend gridstack with our own custom method GridStack.prototype.printCount = function() { console.log('grid has ' + this.engine.nodes.length + ' items'); }; let grid = GridStack.init(); // you can now call grid.printCount(); ``` ## Extend Engine You can now (5.1+) easily create your own layout engine to further customize your usage. Here is a typescript example ```ts import { GridStack, GridStackEngine, GridStackNode, GridStackMoveOpts } from 'gridstack'; class CustomEngine extends GridStackEngine { /** refined this to move the node to the given new location */ public override moveNode(node: GridStackNode, o: GridStackMoveOpts): boolean { // keep the same original X and Width and let base do it all... o.x = node.x; o.w = node.w; return super.moveNode(node, o); } } GridStack.registerEngine(CustomEngine); // globally set our custom class ``` ## Change grid columns GridStack makes it very easy if you need [1-12] columns out of the box (default is 12), but you always need **2 things** if you need to customize this: 1) Change the `column` grid option when creating a grid to your number N ```js GridStack.init( {column: N} ); ``` NOTE: step 2 is OLD and not needed with v12+ which uses CSS variables instead of classes 2) also include `gridstack-extra.css` if **N < 12** (else custom CSS - see next). Without these, things will not render/work correctly. ```html
...
``` Note: class `.grid-stack-N` will automatically be added and we include `gridstack-extra.min.css` which defines CSS for grids with custom [2-11] columns. Anything more and you'll need to generate the SASS/CSS yourself (see next). See example: [2 grids demo](http://gridstack.github.io/gridstack.js/demo/two.html) with 6 columns ## Custom columns CSS (OLD, not needed with v12+) NOTE: step is OLD and not needed with v12+ which uses CSS variables instead of classes If you need > 12 columns or want to generate the CSS manually you will need to generate CSS rules for `.grid-stack-item[gs-w="X"]` and `.grid-stack-item[gs-x="X"]`. For instance for 4-column grid you need CSS to be: ```css .gs-4 > .grid-stack-item[gs-x="1"] { left: 25% } .gs-4 > .grid-stack-item[gs-x="2"] { left: 50% } .gs-4 > .grid-stack-item[gs-x="3"] { left: 75% } .gs-4 > .grid-stack-item { width: 25% } .gs-4 > .grid-stack-item[gs-w="2"] { width: 50% } .gs-4 > .grid-stack-item[gs-w="3"] { width: 75% } .gs-4 > .grid-stack-item[gs-w="4"] { width: 100% } ``` Better yet, here is a SCSS code snippet, you can use sites like [sassmeister.com](https://www.sassmeister.com/) to generate the CSS for you instead: ```scss $columns: 20; @function fixed($float) { @return round($float * 1000) / 1000; // total 2+3 digits being % } .gs-#{$columns} > .grid-stack-item { width: fixed(100% / $columns); @for $i from 1 through $columns - 1 { &[gs-x='#{$i}'] { left: fixed((100% / $columns) * $i); } &[gs-w='#{$i+1}'] { width: fixed((100% / $columns) * ($i+1)); } } } ``` you can also use the SCSS [src/gridstack-extra.scss](https://github.com/gridstack/gridstack.js/tree/master/src/gridstack-extra.scss) included in NPM package and modify to add more columns. Sample gulp command for 30 columns: ```js gulp.src('node_modules/gridstack/dist/src/gridstack-extra.scss') .pipe(replace('$start: 2 !default;','$start: 30;')) .pipe(replace('$end: 11 !default;','$end: 30;')) .pipe(sass({outputStyle: 'compressed'})) .pipe(rename({extname: '.min.css'})) .pipe(gulp.dest('dist/css')) ``` ## Override resizable/draggable options You can override default `resizable`/`draggable` options. For instance to enable other then bottom right resizing handle you can init gridstack like: ```js GridStack.init({ resizable: { handles: 'e,se,s,sw,w' } }); ``` ## Touch devices support gridstack v6+ now support mobile out of the box, with the addition of native touch event (along with mouse event) for drag&drop and resize. Older versions (3.2+) required the jq version with added touch punch, but doesn't work well with nested grids. This option is now the default: ```js let options = { alwaysShowResizeHandle: 'mobile' // true if we're on mobile devices }; GridStack.init(options); ``` See [example](http://gridstack.github.io/gridstack.js/demo/mobile.html). # Migrating ## Migrating to v0.6 starting in 0.6.x `change` event are no longer sent (for pretty much most nodes!) when an item is just added/deleted unless it also changes other nodes (was incorrect and causing inefficiencies). You may need to track `added|removed` [events](https://github.com/gridstack/gridstack.js/tree/master/doc#events) if you didn't and relied on the old broken behavior. ## Migrating to v1 v1.0.0 removed Jquery from the API and external dependencies, which will require some code changes. Here is a list of the changes: 0. see previous step if not on v0.6 already 1. your code only needs to `import GridStack from 'gridstack'` or include `gridstack.all.js` and `gristack.css` (don't include other JS) and is recommended you do that as internal dependencies will change over time. If you are jquery based, see [jquery app](#jquery-application) section. 2. code change: **OLD** initializing code + adding a widget + adding an event: ```js // initialization returned Jquery element, requiring second call to get GridStack var var grid = $('.grid-stack').gridstack(opts?).data('gridstack'); // returned Jquery element grid.addWidget($('
test
'), undefined, undefined, 2, undefined, true); // jquery event handler $('.grid-stack').on('added', function(e, items) {/* items contains info */}); // grid access after init var grid = $('.grid-stack').data('gridstack'); ``` **NEW** ```js // element identifier defaults to '.grid-stack', returns the grid // Note: for Typescript use window.GridStack.init() until next native 2.x TS version var grid = GridStack.init(opts?, element?); // returns DOM element grid.addWidget('
test
', {width: 2}); // Note: in 3.x it's ever simpler // grid.addWidget({w:2, content: 'test'}) // event handler grid.on('added', function(e, items) {/* items contains info */}); // grid access after init var grid = el.gridstack; // where el = document.querySelector('.grid-stack') or other ways... ``` Other rename changes ```js `GridStackUI` --> `GridStack` `GridStackUI.GridStackEngine` --> `GridStack.Engine` `grid.container` (jquery grid wrapper) --> `grid.el` // (grid DOM element) `grid.grid` (GridStackEngine) --> `grid.engine` `grid.setColumn(N)` --> `grid.column(N)` and `grid.column()` // to get value, old API still supported though ``` Recommend looking at the [many samples](./demo) for more code examples. ## Migrating to v2 make sure to read v1 migration first! v2 is a Typescript rewrite of 1.x, removing all jquery events, using classes and overall code cleanup to support ES6 modules. Your code might need to change from 1.x 1. In general methods that used no args (getter) vs setter can't be used in TS when the arguments differ (set/get are also not function calls so API would have changed). Instead we decided to have all set methods return `GridStack` to they can be chain-able (ex: `grid.float(true).cellHeight(10).column(6)`). Also legacy methods that used to take many parameters will now take a single object (typically `GridStackOptions` or `GridStackWidget`). ```js `addWidget(el, x, y, width, height)` --> `addWidget(el, {with: 2})` // Note: in 2.1.x you can now just do addWidget({with: 2, content: "text"}) `float()` --> `getFloat()` // to get value `cellHeight()` --> `getCellHeight()` // to get value `verticalMargin` --> `margin` // grid options and API that applies to all 4 sides. `verticalMargin()` --> `getMargin()` // to get value ``` 2. event signatures are generic and not jquery-ui dependent anymore. `gsresizestop` has been removed as `resizestop|dragstop` are now called **after** the DOM attributes have been updated. 3. `oneColumnMode` would trigger when `window.width` < 768px by default. We now check for grid width instead (more correct and supports nesting). You might need to adjust grid `oneColumnSize` or `disableOneColumnMode`. **Note:** 2.x no longer support legacy IE11 and older due to using more compact ES6 output and typecsript native code. You will need to stay at 1.x ## Migrating to v3 make sure to read v2 migration first! v3 has a new HTML5 drag&drop plugging (63k total, all native code), while still allowing you to use the legacy jquery-ui version instead (188k), or a new static grid version (34k, no user drag&drop but full API support). You will need to decide which version to use as `gridstack.all.js` no longer exist (same is now `gridstack-jq.js`) - see [include info](#include). **NOTE**: HTML5 version is almost on parity with the old jquery-ui based drag&drop. the `containment` (prevent a child from being dragged outside it's parent) and `revert` (not clear what it is for yet) are not yet implemented in initial release of v3.0.0.
Also mobile devices don't support h5 `drag` events (will need to handle `touch`) whereas v3.2 jq version now now supports out of the box (see [v3.2 release](https://github.com/gridstack/gridstack.js/releases/tag/v3.2.0)) Breaking changes: 1. include (as mentioned) need to change 2. `GridStack.update(el, opt)` now takes single `GridStackWidget` options instead of only supporting (x,y,w,h) BUT legacy call in JS will continue working the same for now. That method is a complete re-write and does the right constrain and updates now for all the available params. 3. `locked()`, `move()`, `resize()`, `minWidth()`, `minHeight()`, `maxWidth()`, `maxHeight()` methods are hidden from Typescript (JS can still call for now) as they are just 1 liner wrapper around `update(el, opt)` anyway and will go away soon. (ex: `move(el, x, y)` => `update(el, {x, y})`) 4. item attribute like `data-gs-min-width` is now `gs-min-w`. We removed 'data-' from all attributes, and shorten 'width|height' to just 'w|h' to require less typing and more efficient (2k saved in .js alone!). 5. `GridStackWidget` used in most API `width|height|minWidth|minHeight|maxWidth|maxHeight` are now shorter `w|h|minW|minH|maxW|maxH` as well ## Migrating to v4 make sure to read v3 migration first! v4 is a complete re-write of the collision and drag in/out heuristics to fix some very long standing request & bugs. It also greatly improved usability. Read the release notes for more detail. **Unlikely** Breaking Changes (internal usage): 1. `removeTimeout` was removed (feedback over trash will be immediate - actual removal still on mouse up) 2. the following `GridStackEngine` methods changed (used internally, doesn't affect `GridStack` public API) ```js // moved to 3 methods with new option params to support new code and pixel coverage check `collision()` -> `collide(), collideAll(), collideCoverage()` `moveNodeCheck(node, x, y, w, h)` -> `moveNodeCheck(node, opt: GridStackMoveOpts)` `isNodeChangedPosition(node, x, y, w, h)` -> `changedPosConstrain(node, opt: GridStackMoveOpts)` `moveNode(node, x, y, w, h, noPack)` -> `moveNode(node, opt: GridStackMoveOpts)` ``` 3. removed old obsolete (v0.6-v1 methods/attrs) `getGridHeight()`, `verticalMargin`, `data-gs-current-height`, `locked()`, `maxWidth()`, `minWidth()`, `maxHeight()`, `minHeight()`, `move()`, `resize()` ## Migrating to v5 make sure to read v4 migration first! v5 does not have any breaking changes from v4, but a focus on nested grids in h5 mode: You can now drag in/out of parent into nested child, with new API parameters values. See the release notes. ## Migrating to v6 the API did not really change from v5, but a complete re-write of Drag&Drop to use native `mouseevent` (instead of HTML draggable=true which is buggy on Mac Safari, and doesn't work on mobile devices) and `touchevent` (mobile), and we no longer have jquery ui option (wasn't working well for nested grids, didn't want to maintain legacy lib). The main difference is you only need to include gridstack.js and get D&D (desktop and mobile) out of the box for the same size as h5 version. ## Migrating to v7 New addition, no API breakage per say. See release notes about creating sub-grids on the fly. ## Migrating to v8 Possible breaking change if you use nested grid JSON format, or original Angular wrapper, or relied on specific CSS paths. Also target is now ES2020 (see release notes). * `GridStackOptions.subGrid` -> `GridStackOptions.subGridOpts` rename. We now have `GridStackWidget.subGridOpts` vs `GridStackNode.subGrid` (was both types which is error prone) * `GridStackOptions.addRemoveCB` -> `GridStack.addRemoveCB` is now global instead of grid option * removed `GridStackOptions.dragInOptions` since `GridStack.setupDragIn()` has it replaced since 4.0 * remove `GridStackOptions.minWidth` obsolete since 5.1, use `oneColumnSize` instead * CSS rules removed `.grid-stack` prefix for anything already gs based, 12 column (default) now uses `.gs-12`, extra.css is less than 1/4th it original size!, `gs-min|max_w|h` attribute no longer written (but read) ## Migrating to v9 New addition - see release notes about `sizeToContent` feature. Possible break: * `GridStack.onParentResize()` is now called `onResize()` as grid now directly track size change, no longer involving parent per say to tell us anything. Note sure why it was public. ## Migrating to v10 we now support much richer responsive behavior with `GridStackOptions.columnOpts` including any breakpoint width:column pairs, or automatic column sizing. breaking change: * `disableOneColumnMode`, `oneColumnSize` have been removed (thought we temporary convert if you have them). use `columnOpts: { breakpoints: [{w:768, c:1}] }` for the same behavior. * 1 column mode switch is no longer by default (`columnOpts` is not defined) as too many new users had issues. Instead set it explicitly (see above). * `oneColumnModeDomSort` has been removed. Planning to support per column layouts at some future times. TBD ## Migrating to v11 * All instances of `el.innerHTML = 'some content'` have been removed for security reason as it opens up some potential for accidental XSS. * Side panel drag&drop complete rewrite. * new lazy loading option **Breaking change:** * V11 add new `GridStack.renderCB` that is called for you to create the widget content (entire GridStackWidget is passed so you can use id or some other field as logic) while GS creates the 2 needed parent divs + classes, unlike `GridStack.addRemoveCB` which doesn't create anything for you. Both can be handy for Angular/React/Vue frameworks. * `addWidget(w: GridStackWidget)` is now the only supported format, no more string content passing. You will need to create content yourself as shown below, OR use `GridStack.createWidgetDivs()` to create parent divs, do the innerHtml, then call `makeWidget(el)` instead. * if your code relies on `GridStackWidget.content` with real HTML (like a few demos) it is up to you to do this: ```ts // NOTE: REAL apps would sanitize-html or DOMPurify before blinding setting innerHTML. see #2736 GridStack.renderCB = function(el: HTMLElement, w: GridStackNode) { el.innerHTML = w.content; }; // now you can create widgets like this again let gridWidget = grid.addWidget({x, y, w, h, content: '
My html content
'}); ``` **Potential breaking change:** * BIG overall to how sidepanel helper drag&drop is done: 1. `clone()` helper is now passed full HTML element dragged, not an event on `grid-stack-item-content` so you can clone or set attr at the top. 2. use any class/structure you want for side panel items (see two.html) 3. `GridStack.setupDragIn()` now support associating a `GridStackWidget` for each sidepanel that will be used to define what to create on drop! 4. if no `GridStackWidget` is defined, the helper will now be inserted as is, and NOT original sidepanel item. 5. support DOM gs- attr as well as gridstacknode JSON (see two.html) alternatives. ## Migrating to v12 * column and cell height code has been re-writen to use browser CSS variables, and we no longer need a tons of custom CSS classes! this fixes a long standing issue where people forget to include the right CSS for non 12 columns layouts, and a big speedup in many cases (many columns, or small cellHeight values). **Potential breaking change:** * `gridstack-extra.min.css` no longer exist, nor is custom column CSS classes needed. API/options hasn't changed. * (v12.1) `ES5` folder content has been removed - was for IE support, which has been dropped. * (v12.1) nested grid events are now sent to the main grid. You might have to adjust your workaround of this missing feature. nested.html demo has been adjusted. # jQuery Application This is **old and no longer apply to v6+**. You'll need to use v5.1.1 and before ```js import 'gridstack/dist/gridstack.min.css'; import { GridStack } from 'gridstack'; import 'gridstack/dist/jq/gridstack-dd-jqueryui'; ``` **Note**: `jquery` & `jquery-ui` are imported by name, so you will have to specify their location in your webpack (or equivalent) config file, which means you can possibly bring your own version ```js alias: { 'jquery': 'gridstack/dist/jq/jquery.js', 'jquery-ui': 'gridstack/dist/jq/jquery-ui.js', 'jquery.ui': 'gridstack/dist/jq/jquery-ui.js', 'jquery.ui.touch-punch': 'gridstack/dist/jq/jquery.ui.touch-punch.js', }, ``` Alternatively (single combined file) in html ```html ``` We have a native HTML5 drag'n'drop through the plugin system (default), but the jquery-ui version can be used instead. It will bundle `jquery` (3.5.1) + `jquery-ui` (1.13.1 minimal drag|drop|resize) + `jquery-ui-touch-punch` (1.0.8 for mobile support) in `gridstack-jq.js`. **NOTE: in v4, v3**: we ES6 module import jquery & jquery-ui by name, so you need to specify location of those .js files, which means you might be able to bring your own version as well. See the include instructions. **NOTE: in v1.x** IFF you want to use gridstack-jq instead and your app needs to bring your own JQ version, you should **instead** include `gridstack-poly.min.js` (optional IE support) + `gridstack.min.js` + `gridstack.jQueryUI.min.js` after you import your JQ libs. But note that there are issue with jQuery and ES6 import (see [1306](https://github.com/gridstack/gridstack.js/issues/1306)). As for events, you can still use `$(".grid-stack").on(...)` for the version that uses jquery-ui for things we don't support. # Changes View our change log [here](https://github.com/gridstack/gridstack.js/tree/master/doc/CHANGES.md). # Usage Trend [Usage Trend of gridstack](https://npm-compare.com/gridstack#timeRange=THREE_YEARS) NPM Usage Trend of gridstack # The Team gridstack.js is currently maintained by [Alain Dumesny](https://github.com/adumesny), before that [Dylan Weiss](https://github.com/radiolips), originally created by [Pavel Reznikov](https://github.com/troolee).

Install "Vitest" extension 2. Run tests directly from editor 3. Set breakpoints and debug ### Browser UI ```bash yarn test:ui ``` Opens a web interface for: - Running individual tests - Viewing test results - Coverage visualization - Real-time updates ## Performance ### Speed Comparison - **Karma + Jasmine**: ~15-20 seconds - **Vitest**: ~3-5 seconds - **Watch Mode**: Sub-second re-runs ### Optimization Tips - Use `vi.mock()` for heavy dependencies - Prefer `toBe()` over `toEqual()` for primitives - Group related tests in `describe` blocks - Use `beforeEach`/`afterEach` for setup/cleanup ## Migration Notes This project was migrated from Karma + Jasmine to Vitest with the following changes: 1. **Dependencies**: Removed karma-\* packages, added vitest + utilities 2. **Configuration**: Replaced `karma.conf.js` with `vitest.config.ts` 3. **Syntax**: Updated test syntax to modern ES6+ style 4. **Coverage**: Enhanced coverage with V8 provider and multiple formats 5. **Scripts**: New npm scripts for various testing workflows All existing tests were preserved and converted to work with Vitest. ================================================ FILE: angular/.editorconfig ================================================ # Editor configuration, see https://editorconfig.org root = true [*] charset = utf-8 indent_style = space indent_size = 2 insert_final_newline = true trim_trailing_whitespace = true [*.ts] quote_type = single [*.md] max_line_length = off trim_trailing_whitespace = false ================================================ FILE: angular/.gitignore ================================================ # See http://help.github.com/ignore-files/ for more about ignoring files. # Compiled output /dist /tmp /out-tsc /bazel-out /doc/html/ # Node /node_modules npm-debug.log yarn-error.log # IDEs and editors .idea/ .project .classpath .c9/ *.launch .settings/ *.sublime-workspace # Visual Studio Code .vscode/* !.vscode/settings.json !.vscode/tasks.json !.vscode/launch.json !.vscode/extensions.json .history/* # Miscellaneous /.angular/cache .sass-cache/ /connect.lock /coverage /libpeerconnection.log testem.log /typings # System files .DS_Store Thumbs.db ================================================ FILE: angular/README.md ================================================ # Angular wrapper The Angular [wrapper component](projects/lib/src/lib/gridstack.component.ts) is a better way to use Gridstack, but alternative raw [ngFor](projects/demo/src/app/ngFor.ts) or [simple](projects/demo/src/app/simple.ts) demos are also given. Running version can be seen here https://stackblitz.com/edit/gridstack-angular # Dynamic grid items this is the recommended way if you are going to have multiple grids (alow drag&drop between) or drag from toolbar to create items, or drag to remove items, etc... I.E. don't use Angular templating to create grid items as that is harder to sync when gridstack will also add/remove items. MyComponent HTML ```html ``` MyComponent CSS ```css @import "gridstack/dist/gridstack.min.css"; .grid-stack { background: #fafad2; } .grid-stack-item-content { text-align: center; background-color: #18bc9c; } ``` Standalone MyComponent Code ```ts import { GridStackOptions } from 'gridstack'; import { GridstackComponent, GridstackItemComponent } from 'gridstack/dist/angular'; @Component({ imports: [ // SKIP if doing module import instead (next) GridstackComponent, GridstackItemComponent ] ... }) export class MyComponent { // sample grid options + items to load... public gridOptions: GridStackOptions = { margin: 5, children: [ // or call load(children) or addWidget(children[0]) with same data {x:0, y:0, minW:2, content:'Item 1'}, {x:1, y:0, content:'Item 2'}, {x:0, y:1, content:'Item 3'}, ] } } ``` IF doing module import instead of standalone, you will also need this: ```ts import { GridstackModule } from 'gridstack/dist/angular'; @NgModule({ imports: [GridstackModule, ...] ... bootstrap: [AppComponent] }) export class AppModule { } ``` # More Complete example In this example (build on previous one) will use your actual custom angular components inside each grid item (instead of dummy html content) and have per component saved settings as well (using BaseWidget). HTML ```html
message when grid is empty
 ``` Code ```ts import { Component } from '@angular/core'; import { GridStack, GridStackOptions } from 'gridstack'; import { GridstackComponent, gsCreateNgComponents, NgGridStackWidget, nodesCB, BaseWidget } from 'gridstack/dist/angular'; // some custom components @Component({ selector: 'app-a', template: 'Comp A {{text}}', }) export class AComponent extends BaseWidget implements OnDestroy { @Input() text: string = 'foo'; // test custom input data public override serialize(): NgCompInputs | undefined { return this.text ? {text: this.text} : undefined; } ngOnDestroy() { console.log('Comp A destroyed'); // test to make sure cleanup happens } } @Component({ selector: 'app-b', template: 'Comp B', }) export class BComponent extends BaseWidget { } // ...in your module (classic), OR your ng19 app.config provideEnvironmentInitializer call this: constructor() { // register all our dynamic components types created by the grid GridstackComponent.addComponentToSelectorType([AComponent, BComponent]) ; } // now our content will use Components instead of dummy html content public gridOptions: NgGridStackOptions = { margin: 5, minRow: 1, // make space for empty message children: [ // or call load()/addWidget() with same data {x:0, y:0, minW:2, selector:'app-a'}, {x:1, y:0, minW:2, selector:'app-a', input: { text: 'bar' }}, // custom input that works using BaseWidget.deserialize() Object.assign(this, w.input) {x:2, y:0, selector:'app-b'}, {x:3, y:0, content:'plain html'}, ] } // called whenever items change size/position/etc.. see other events public onChange(data: nodesCB) { console.log('change ', data.nodes.length > 1 ? data.nodes : data.nodes[0]); } ``` # ngFor with wrapper For simple case where you control the children creation (gridstack doesn't do create or re-parenting) HTML ```html @for (n of items; track n.id) { Item {{n.id}} } Item {{n.id}} ``` Code ```javascript import { GridStackOptions, GridStackWidget } from 'gridstack'; import { nodesCB } from 'gridstack/dist/angular'; /** sample grid options and items to load... */ public gridOptions: GridStackOptions = { margin: 5 } public items: GridStackWidget[] = [ {x:0, y:0, minW:2, id:'1'}, // must have unique id used for trackBy {x:1, y:0, id:'2'}, {x:0, y:1, id:'3'}, ]; // called whenever items change size/position/etc.. public onChange(data: nodesCB) { console.log('change ', data.nodes.length > 1 ? data.nodes : data.nodes[0]); } // ngFor unique node id to have correct match between our items used and GS public identify(index: number, w: GridStackWidget) { return w.id; // or use index if no id is set and you only modify at the end... } ``` ## Demo You can see a fuller example at [app.component.ts](projects/demo/src/app/app.component.ts) to build the demo, go to [angular/projects/demo](projects/demo/) and run `yarn` + `yarn start` and navigate to `http://localhost:4200/` Code started shipping with v8.1.2+ in `dist/angular` for people to use directly and is an angular module! (source code under `dist/angular/src`) ## Caveats - This wrapper needs: - gridstack v8+ to run as it needs the latest changes (use older version that matches GS versions) - Angular 14+ for dynamic `createComponent()` API and Standalone Components (verified against 19+) NOTE: if you are on Angular 13 or below: copy the wrapper code over (or patch it - see main page example) and change `createComponent()` calls to use old API instead: NOTE2: now that we're using standalone, you will also need to remove `standalone: true` and `imports` on each component so you will to copy those locally (or use <11.1.2 version) ```ts protected resolver: ComponentFactoryResolver, ... const factory = this.resolver.resolveComponentFactory(GridItemComponent); const gridItemRef = grid.container.createComponent(factory) as ComponentRef; // ...do the same for widget selector... ``` ## ngFor Caveats - This wrapper handles well ngFor loops, but if you're using a trackBy function (as I would recommend) and no element id change after an update, you must manually update the `GridstackItemComponent.option` directly - see [modifyNgFor()](./projects/demo/src/app/app.component.ts#L202) example. - The original client list of items is not updated to match **content** changes made by gridstack (TBD later), but adding new item or removing (as shown in demo) will update those new items. Client could use change/added/removed events to sync that list if they wish to do so. Would appreciate getting help doing the same for React and Vue (2 other popular frameworks) -Alain ================================================ FILE: angular/README_build.md ================================================ # GridstackLib This project was generated with [Angular CLI](https://github.com/angular/angular-cli) version 14.2.10. ## Development server Run `ng serve` for a dev server.

Pick a demo to load:

COMPONENT template: using DOM template to use components statically

item 1 item 2 wide

COMPONENT ngFor: Most complete example that uses Component wrapper for grid and gridItem

COMPONENT dynamic: Best example that uses Component wrapper and dynamic grid creation (drag between grids, from toolbar, etc...)

Nested Grid: shows nested component grids, like nested.html demo but with Ng Components

Drag nested
Comp N nested
Add items here or reload the grid

two.html: shows multiple grids, sidebar creating Components

will be A
will be B max=3

open console and scroll to see delay loading of components

load() + clear() to memory leak test between the two

Using GridStack.js with React hooks

As with any virtual DOM based framework, you need to check if React has rendered the DOM (or any updates to it) before you initialize GridStack or call its methods. This example shows how to make rendered components widgets:

  1. Render items, each with a reference
  2. Convert each rendered item to a widget using the reference and the makeWidget() function

How to integrate GridStack.js with Vue.js

As with any virtual DOM based framework, you need to check if Vue has rendered the DOM (or any updates to it) before you initialize GridStack or call its methods. As a basic example, check this component's mounted hook.

If your app requires more complex render logic than the inline template in `addWidget`, consider makeWidget to let Vue deal with DOM rendering.

Please copy the relevant code to your project to use it. ```tsx import { GridStackProvider, GridStackRender, GridStackRenderProvider, } from "path/to/lib"; import "gridstack/dist/gridstack.css"; import "path/to/demo.css"; function Text({ content }: { content: string }) { return
{content}
; } const COMPONENT_MAP = { Text, // ... other components }; // Grid options const gridOptions = { acceptWidgets: true, margin: 8, cellHeight: 50, children: [ { id: "item1", h: 2, w: 2, content: JSON.stringify({ name: "Text", props: { content: "Item 1" }, }), }, // ... other grid items ], }; function App() { return ( ); } ``` ## Advanced Features ### Toolbar Operations Provide APIs to add new components and sub-grids: ```tsx function Toolbar() { const { addWidget, addSubGrid } = useGridStackContext(); return (
); } ``` ### Layout Saving Get the current layout: ```tsx const { saveOptions } = useGridStackContext(); const currentLayout = saveOptions(); ``` ## API Reference ### GridStackProvider The main context provider, accepts the following properties: - `initialOptions`: Initial configuration options for GridStack ### GridStackRender The core component for rendering the grid, accepts the following properties: - `componentMap`: A mapping from component names to actual React components ### Hooks - `useGridStackContext()`: Access GridStack context and operations - `addWidget`: Add a new component - `addSubGrid`: Add a new sub-grid - `saveOptions`: Save current layout - `initialOptions`: Initial configuration options ================================================ FILE: react/eslint.config.js ================================================ import js from '@eslint/js' import globals from 'globals' import reactHooks from 'eslint-plugin-react-hooks' import reactRefresh from 'eslint-plugin-react-refresh' import tseslint from 'typescript-eslint' export default tseslint.config( { ignores: ['dist'] }, { extends: [js.configs.recommended, ...tseslint.configs.recommended], files: ['**/*.{ts,tsx}'], languageOptions: { ecmaVersion: 2020, globals: globals.browser, }, plugins: { 'react-hooks': reactHooks, 'react-refresh': reactRefresh, }, rules: { ...reactHooks.configs.recommended.rules, 'react-refresh/only-export-components': [ 'warn', { allowConstantExport: true }, ], }, }, ) ================================================ FILE: react/index.html ================================================ Vite + React + TS
