Get complete control over drag and drop behaviour with Draggable! Draggable abstracts
native browser events into a comprehensive API to create a custom drag and drop experience.
`Draggable` comes with additional modules: `Sortable`, `Droppable`, `Swappable`. Draggable
itself does not perform any sorting behaviour while dragging, but does the heavy lifting, e.g.
creates mirror, emits events, manages sensor events, makes elements draggable.

The additional modules are built on top of `Draggable` and therefore provide a similar API
interface, for more information read the documentation below.

**Features**

- Works with native drag, mouse, touch and force touch events
- Can extend dragging behaviour by hooking into draggables event life cycle
- Can extend drag detection by adding sensors to draggable
- The library is targeted ES6 first

## Running examples

To run the `examples` project locally, simply run the following from the `draggable` root:

```
yarn && yarn start
```

This will start a server that hosts the contents of `examples/`. It also watches for file
changes from both `src/` and `examples/src` and reloads the browser.

## Contributing

Contributions are more than welcome, the code base is still new and needs more love.

For more information, please checkout the [contributing document](https://github.com/Shopify/draggable/blob/master/CONTRIBUTING.md).

## Roadmap

We are currently working on `v1.0.0-beta.11`. Check out the [project board](https://github.com/Shopify/draggable/projects/3) to see tasks and follow progress on the release. Any Pull Requests should be pointed against the feature branch `v1.0.0-beta.11`.
