# Contributing

Hey there! Glad you want to chime in. Here's what you need to know.

### Support Requests

We have a [dedicated support channel in Slack][4]. See [this issue][3] to get an invite. Support requests won't be handled through the repository.

If you have a question, make sure it wasn't [already answered][1]. If it wasn't, please refer to the Slack chat. To get an invite, use the badge in the [demo page][2].

> Our goal is to provide answers to the most frequently asked questions somewhere in the documentation.

### Bugs

Bug reports are tricky. Please provide as much context as possible, and if you want to start working on a fix, we'll be forever grateful! Please try and test around for a bit to make sure you're dealing with a bug and not an issue in your implementation.

If possible, provide a demo where the bug is isolated and turned into its smallest possible representation. That would help a lot!

Thanks for reporting bugs, we'd be lost without you.

### Feature Requests

We're still considering feature requests. Note that we might not implement the feature you want, or exactly how you want it. The goal here is to keep making `dragula` awesome while not making it too bloated.

We also dislike overly specific features and favor more abstract ones you the consumer can build other features upon.

# Development

Development flows are based on `npm run` scripts.

### Build

To compile a standalone browserify module, use the following command. A minified version will also be produced. The compiled bundles are placed inside `dist`. Since **these are autogenerated**, please don't include them in your pull requests.

```shell
npm run build
```

You can also run the build continuously, _to facilitate development_, with this command.

```shell
npm start
```

### Test

Run the command below to execute all tests in a DevTools window through Electron. Note that the DevTools will get reloaded whenever your test files change, making tests a breeze!

```shell
npm run test-watch
```

To run tests a single time, simply run the following command. This is used in CI testing.

```shell
npm test
```

> Drag and drop so simple it hurts

Browser support includes every sane browser and **IE7+**. <sub>_(Granted you polyfill the functional `Array` methods in ES5)_</sub>

Framework support includes vanilla JavaScript, Angular, and React.

- Official [Angular bridge][8] for `dragula` [_(demo)_][10]
- Official [Angular 2 bridge][22] for `dragula` [_(demo)_][23]
- Official [React bridge][9] for `dragula` [_(demo)_][11]

# Demo

[![demo.png][1]][2]

Try out the [demo][2]!

# Inspiration

Have you ever wanted a drag and drop library that just works? That doesn't just depend on bloated frameworks, that has great support? That actually understands where to place the elements when they are dropped? That doesn't need you to do a zillion things to get it to work? Well, so did I!

# Features

- Super easy to set up
- No bloated dependencies
- **Figures out sort order** on its own
- A shadow where the item would be dropped offers **visual feedback**
- Touch events!
- Seamlessly handles clicks *without any configuration*

# Install

You can get it on npm.

```shell
npm install dragula --save
```

Or a CDN.

```shell
<script src='https://cdnjs.cloudflare.com/ajax/libs/dragula/$VERSION/dragula.min.js'></script>
```

If you're not using either package manager, you can use `dragula` by downloading the [files in the `dist` folder][15]. We **strongly suggest** using `npm`, though.

##### Including the JavaScript

There's a caveat to `dragula`. You shouldn't include it in the `<head>` of your web applications. It's bad practice to place scripts in the `<head>`, and as such `dragula` makes no effort to support this use case.

Place `dragula` in the `<body>`, instead.

##### Including the CSS!

There's [a few CSS styles][16] you need to incorporate in order for `dragula` to work as expected.

You can add them by including [`dist/dragula.css`][12] or [`dist/dragula.min.css`][13] in your document. If you're using Stylus, you can include the styles using the directive below.

```styl
@import 'node_modules/dragula/dragula'
```

# Usage

Dragula provides the easiest possible API to make drag and drop a breeze in your applications.

## `dragula(containers?, options?)`

By default, `dragula` will allow the user to drag an element in any of the `containers` and drop it in any other container in the list. If the element is dropped anywhere that's not one of the `containers`, the event will be gracefully cancelled according to the `revertOnSpill` and `removeOnSpill` options.

Note that dragging is only triggered on left clicks, and only if no meta keys are pressed.

The example below allows the user to drag elements from `left` into `right`, and from `right` into `left`.

```js
dragula([document.querySelector('#left'), document.querySelector('#right')]);
```

You can also provide an `options` object. Here's an **overview of the default values**.

```js
dragula(containers, {
  isContainer: function (el) {
    return false; // only elements in drake.containers will be taken into account
  },
  moves: function (el, source, handle, sibling) {
    return true; // elements are always draggable by default
  },
  accepts: function (el, target, source, sibling) {
    return true; // elements can be dropped in any of the `containers` by default
  },
  invalid: function (el, handle) {
    return false; // don't prevent any drags from initiating by default
  },
  direction: 'vertical',             // Y axis is considered when determining where an element would be dropped
  copy: false,                       // elements are moved by default, not copied
  copySortSource: false,             // elements in copy-source containers can be reordered
  revertOnSpill: false,              // spilling will put the element back where it was dragged from, if this is true
  removeOnSpill: false,              // spilling will `.remove` the element, if this is true
  mirrorContainer: document.body,    // set the element that gets mirror elements appended
  ignoreInputTextSelection: true,     // allows users to select input text, see details below
  slideFactorX: 0,               // allows users to select the amount of movement on the X axis before it is considered a drag instead of a click
  slideFactorY: 0,               // allows users to select the amount of movement on the Y axis before it is considered a drag instead of a click
});
```

You can omit the `containers` argument and add containers dynamically later on.

```js
var drake = dragula({
  copy: true
});
drake.containers.push(container);
```

You can also set the `containers` from the `options` object.

```js
var drake = dragula({ containers: containers });
```

And you could also not set any arguments, which defaults to a drake without containers and with the default options.

```js
var drake = dragula();
```

The options are detailed below.

#### `options.containers`

Setting this option is effectively the same as passing the containers in the first argument to `dragula(containers, options)`.

#### `options.isContainer`

Besides the containers that you pass to `dragula`, or the containers you dynamically `push` or `unshift` from [drake.containers](#drakecontainers), you can also use this method to specify any sort of logic that defines what is a container for this particular `drake` instance.

The example below dynamically treats all DOM elements with a CSS class of `dragula-container` as dragula containers for this `drake`.

```js
var drake = dragula({
  isContainer: function (el) {
    return el.classList.contains('dragula-container');
  }
});
```

#### `options.moves`

You can define a `moves` method which will be invoked with `(el, source, handle, sibling)` whenever an element is clicked. If this method returns `false`, a drag event won't begin, and the event won't be prevented either. The `handle` element will be the original click target, which comes in handy to test if that element is an expected _"drag handle"_.

#### `options.accepts`

You can set `accepts` to a method with the following signature: `(el, target, source, sibling)`. It'll be called to make sure that an element `el`, that came from container `source`, can be dropped on container `target` before a `sibling` element. The `sibling` can be `null`, which would mean that the element would be placed as the last element in the container. Note that if `options.copy` is set to `true`, `el` will be set to the copy, instead of the originally dragged element.

Also note that **the position where a drag starts is always going to be a valid place where to drop the element**, even if `accepts` returned `false` for all cases.

#### `options.copy`

If `copy` is set to `true` _(or a method that returns `true`)_, items will be copied rather than moved. This implies the following differences:

Event     | Move                                     | Copy
----------|------------------------------------------|---------------------------------------------
`drag`    | Element will be concealed from `source`  | Nothing happens
`drop`    | Element will be moved into `target`      | Element will be cloned into `target`
`remove`  | Element will be removed from DOM         | Nothing happens
`cancel`  | Element will stay in `source`            | Nothing happens

If a method is passed, it'll be called whenever an element starts being dragged in order to decide whether it should follow `copy` behavior or not. Consider the following example.

```js
copy: function (el, source) {
  return el.className === 'you-may-copy-us';
}
```
#### `options.copySortSource`

If `copy` is set to `true` _(or a method that returns `true`)_ and `copySortSource` is `true` as well, users will be able to sort elements in `copy`-source containers.

```js
copy: true,
copySortSource: true
```

#### `options.revertOnSpill`

By default, spilling an element outside of any containers will move the element back to the _drop position previewed by the feedback shadow_. Setting `revertOnSpill` to `true` will ensure elements dropped outside of any approved containers are moved back to the source element where the drag event began, rather than stay at the _drop position previewed by the feedback shadow_.

#### `options.removeOnSpill`

By default, spilling an element outside of any containers will move the element back to the _drop position previewed by the feedback shadow_. Setting `removeOnSpill` to `true` will ensure elements dropped outside of any approved containers are removed from the DOM. Note that `remove` events won't fire if `copy` is set to `true`.

#### `options.direction`

When an element is dropped onto a container, it'll be placed near the point where the mouse was released. If the `direction` is `'vertical'`, the default value, the Y axis will be considered. Otherwise, if the `direction` is `'horizontal'`, the X axis will be considered.

#### `options.invalid`

You can provide an `invalid` method with a `(el, handle)` signature. This method should return `true` for elements that shouldn't trigger a drag. The `handle` argument is the element that was clicked, while `el` is the item that would be dragged. Here's the default implementation, which doesn't prevent any drags.

```js
function invalidTarget (el, handle) {
  return false;
}
```

Note that `invalid` will be invoked on the DOM element that was clicked and every parent up to immediate children of a `drake` container.

As an example, you could set `invalid` to return `false` whenever the clicked element _(or any of its parents)_ is an anchor tag.

```js
invalid: function (el, handle) {
  return el.tagName === 'A';
}
```

#### `options.mirrorContainer`

The DOM element where the mirror element displayed while dragging will be appended to. Defaults to `document.body`.

#### `options.ignoreInputTextSelection`

When this option is enabled, if the user clicks on an input element the drag won't start until their mouse pointer exits the input. This translates into the user being able to select text in inputs contained inside draggable elements, and still drag the element by moving their mouse outside of the input -- so you get the best of both worlds.

This option is enabled by default. Turn it off by setting it to `false`. If its disabled your users won't be able to select text in inputs within `dragula` containers with their mouse.

## API

The `dragula` method returns a tiny object with a concise API. We'll refer to the API returned by `dragula` as `drake`.

#### `drake.containers`

This property contains the collection of containers that was passed to `dragula` when building this `drake` instance. You can `push` more containers and `splice` old containers at will.

#### `drake.dragging`

This property will be `true` whenever an element is being dragged.

#### `drake.start(item)`

Enter drag mode **without a shadow**. This method is most useful when providing complementary keyboard shortcuts to an existing drag and drop solution. Even though a shadow won't be created at first, the user will get one as soon as they click on `item` and start dragging it around. Note that if they click and drag something else, `.end` will be called before picking up the new item.

#### `drake.end()`

Gracefully end the drag event as if using **the last position marked by the preview shadow** as the drop target. The proper `cancel` or `drop` event will be fired, depending on whether the item was dropped back where it was originally lifted from _(which is essentially a no-op that's treated as a `cancel` event)_.

#### `drake.cancel(revert)`

If an element managed by `drake` is currently being dragged, this method will gracefully cancel the drag action. You can also pass in `revert` at the method invocation level, effectively producing the same result as if `revertOnSpill` was `true`.

Note that **a _"cancellation"_ will result in a `cancel` event** only in the following scenarios.

- `revertOnSpill` is `true`
- Drop target _(as previewed by the feedback shadow)_ is the source container **and** the item is dropped in the same position where it was originally dragged from

#### `drake.remove()`

If an element managed by `drake` is currently being dragged, this method will gracefully remove it from the DOM.

#### `drake.on` _(Events)_

The `drake` is an event emitter. The following events can be tracked using `drake.on(type, listener)`:

Event Name | Listener Arguments               | Event Description
-----------|----------------------------------|-------------------------------------------------------------------------------------
`drag`     | `el, source`                     | `el` was lifted from `source`
`dragend`  | `el`                             | Dragging event for `el` ended with either `cancel`, `remove`, or `drop`
`drop`     | `el, target, source, sibling`    | `el` was dropped into `target` before a `sibling` element, and originally came from `source`
`cancel`   | `el, container, source`          | `el` was being dragged but it got nowhere and went back into `container`, its last stable parent; `el` originally came from `source`
`remove`   | `el, container, source`          | `el` was being dragged but it got nowhere and it was removed from the DOM. Its last stable parent was `container`, and originally came from `source`
`shadow`   | `el, container, source`          | `el`, _the visual aid shadow_, was moved into `container`. May trigger many times as the position of `el` changes, even within the same `container`; `el` originally came from `source`
`over`     | `el, container, source`          | `el` is over `container`, and originally came from `source`
`out`      | `el, container, source`          | `el` was dragged out of `container` or dropped, and originally came from `source`
`cloned`   | `clone, original, type`          | DOM element `original` was cloned as `clone`, of `type` _(`'mirror'` or `'copy'`)_. Fired for mirror images and when `copy: true`

#### `drake.canMove(item)`

Returns whether the `drake` instance can accept drags for a DOM element `item`. This method returns `true` when all the conditions outlined below are met, and `false` otherwise.

- `item` is a child of one of the specified containers for `drake`
- `item` passes the pertinent [`invalid`](#optionsinvalid) checks
- `item` passes a `moves` check

#### `drake.destroy()`

Removes all drag and drop events used by `dragula` to manage drag and drop between the `containers`. If `.destroy` is called while an element is being dragged, the drag will be effectively cancelled.

## CSS

Dragula uses only four CSS classes. Their purpose is quickly explained below, but you can check [`dist/dragula.css`][12] to see the corresponding CSS rules.

- `gu-unselectable` is added to the `mirrorContainer` element when dragging. You can use it to style the `mirrorContainer` while something is being dragged.
- `gu-transit` is added to the source element when its mirror image is dragged. It just adds opacity to it.
- `gu-mirror` is added to the mirror image. It handles fixed positioning and `z-index` _(and removes any prior margins on the element)_. Note that the mirror image is appended to the `mirrorContainer`, not to its initial container. Keep that in mind when styling your elements with nested rules, like `.list .item { padding: 10px; }`.
- `gu-hide` is a helper class to apply `display: none` to an element.
