@shopify/draggable
Advanced tools
The JavaScript Drag & Drop library your grandparents warned you about.
Warning: Draggable is currently in beta
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
You can install the library via npm.
npm install @shopify/draggable --save
or via yarn:
yarn add @shopify/draggable
or via CDN
<script src="https://cdn.jsdelivr.net/npm/@shopify/draggable@1.0.0-beta/lib/draggable.js"></script>
new Draggable(containers: Array[HTMLElement]|NodeList, options: Object): Draggable
To create a draggable instance you need to specify the containers that hold draggable items, e.g.
[document.body] would work too. The second argument is an options object, which is described
below.
draggable.on(eventName: String, listener: Function): Draggable
Draggable is an event emitter, so you can register callbacks for events. Draggable
also supports method chaining.
draggable.off(eventName: String, listener: Function): Draggable
You can unregister listeners by using .off(), make sure to provide the same callback.
draggable.trigger(eventName: String, event: AbstractEvent): Draggable
You can trigger events through draggable. This is used to fire events internally or by
extensions of Draggable.
draggable.destroy(): void
Detaches all sensors and listeners, and cleans up after itself.
draggable {String}
A css selector for draggable elements within the containers specified. By default it will
look for an element with .draggable-source class. Default: .draggable-source
handle {String}
Specify a css selector for a handle element if you don't want to allow drag action
on the entire element. Default: null
delay {Number}
If you want to delay a drag:start you can specify delay in milliseconds. This can be useful
for draggable elements within scrollable containers. Default: 0
native {Boolean}
If enabled, Draggable will use the browsers native drag events to detect drag behaviour. By default
it will use mouse events to detect drag behaviour. You can only customize the mirror element when
using mouse events, otherwise mirror will be null in events. Default: false
plugins {Array[Plugin]}
Plugins add behaviour to Draggable by hooking into its life cycle, e.g. one of the default
plugins controls the mirror movement. Default: []
appendTo {String|HTMLElement|Function}
Draggable allows you to specify where the mirror should be appended to. You can specify a css
selector, a HTMLElement or a function that returns a HTMLElement
classes {Object}
Draggable adds classes to elements to indicate state. These classes can be used to add styling
on elements in certain states.
| Name | Description | Cancelable | Cancelable action |
|---|---|---|---|
drag:start | Gets fired when drag action begins | true | Prevents drag start |
drag:move | Gets fired when moving a draggable around | false | - |
drag:over | Gets fired when dragging over other draggable | false | - |
drag:over:container | Gets fired when dragging over other draggable container | false | - |

drag:stop | Gets fired when draggable has been released | false | - |
drag:pressure | Gets fired when using force touch on draggable element | false | - |
mirror:created | Gets fired when draggable mirror gets created | false | - |
mirror:attached | Gets fired when draggable mirror gets attached to DOM | false | - |
mirror:move | Gets fired when draggable mirror moves | true | Stop mirror movement |
| Name | Description | Default |
|---|---|---|
body:dragging | Class added on the document body while dragging | draggable--is-dragging |
container:dragging | Class added on the container where the draggable was picked up from | draggable-container--is-dragging |
source:dragging | Class added on the draggable element that has been picked up | draggable-source--is-dragging |
source:placed | Class added on the draggable element on drag:stop | draggable-source--placed |
container:placed | Class added on the draggable container element on drag:stop | draggable-container--placed |
draggable:over | Class added on draggable element you are dragging over | draggable--over |
container:over | Class added on draggable container element you are dragging over | draggable-container--over |
mirror | Class added on the mirror element | draggable-mirror |
This sample code will make list items draggable:
import {Draggable} from '@shopify/draggable';
new Draggable(document.querySelectorAll('ul'))
.on('drag:start', () => console.log('drag:start'))
.on('drag:move', () => console.log('drag:move'))
.on('drag:stop', () => console.log('drag:stop'));
Sortable allows you to reorder elements. It maintains the order internally and fires
three events on top of the draggable events: sortable:start, sortable:sorted and sortable:stop.
new Sortable(containers: Array[HTMLElement]|NodeList, options: Object): Sortable
To create a sortable instance you need to specify the containers that hold draggable items, e.g.
[document.body] would work too. The second argument is an options object, which is described
below.
sortable.on(eventName: String, listener: Function): Sortable
Sortable uses Draggables event emitter, so you can register callbacks for events. Sortable
also supports method chaining.
sortable.off(eventName: String, listener: Function): Sortable
You can unregister listeners by using .off(), make sure to provide the same callback.
sortable.trigger(eventName: String, event: AbstractEvent): Sortable
You can trigger events through sortable. This is used to fire events internally or by
extensions of Draggable.
sortable.destroy(): void
Detaches all sensors and listeners, and cleans up after itself.
Same as Draggable
| Name | Description | Cancelable | Cancelable action |
|---|---|---|---|
sortable:start | Gets fired when drag action begins | true | Prevents drag start |
sortable:sorted | Gets fired when the source gets sorted in the DOM | false | - |
sortable:stop | Gets fired when dragging over other draggable | false | - |
Same as Draggable
This sample code will make list items draggable:
import {Sortable} from '@shopify/draggable';
new Sortable(document.querySelectorAll('ul'))
.on('sortable:start', () => console.log('sortable:start'))
.on('sortable:sorted', () => console.log('sortable:sorted'))
.on('sortable:stop', () => console.log('sortable:stop'));
Droppable allows you to declare draggable and droppable elements via options.
Droppable fires two events on top of the draggable events: droppable:over and droppable:out.
new Droppable(containers: Array[HTMLElement]|NodeList, options: Object): Droppable
To create a droppable instance you need to specify the containers that hold draggable items, e.g.
[document.body] would work too. The second argument is an options object, which is described
below.
droppable.on(eventName: String, listener: Function): Droppable
Droppable uses Draggables event emitter, so you can register callbacks for events. Droppable
also supports method chaining.
droppable.off(eventName: String, listener: Function): Droppable
You can unregister listeners by using .off(), make sure to provide the same callback.
droppable.trigger(eventName: String, event: AbstractEvent): Droppable
You can trigger events through droppable. This is used to fire events internally or by
extensions of Draggable.
droppable.destroy(): void
Detaches all sensors and listeners, and cleans up after itself.
droppable {String|Array[HTMLElement]|NodeList|Function}
A css selector string, an array of elements, a NodeList or a function returning elements for droppable
elements within the containers specified.
| Name | Description | Cancelable | Cancelable action |
|---|---|---|---|
droppable:over | Gets fired when dragging over droppable element | true | Prevents drop |
droppable:out | Gets fired when dragging out of a droppable element | true | Prevents release |
| Name | Description | Default |
|---|---|---|
droppable:active | Class added on droppables when drag starts | draggable-droppable--active |
droppable:occupied | Class added on droppable element, when it contains a draggable | draggable-droppable--occupied |
This sample code will make list items draggable and allows to drop them inside another element:
import {Droppable} from '@shopify/draggable';
const droppable = new Droppable(document.querySelectorAll('ul'), {
draggable: 'li',
droppable: '#dropzone',
});
droppable.on('droppable:over', () => console.log('droppable:over'))
droppable.on('droppable:out', () => console.log('droppable:out'));
Swappable allows you to swap elements by dragging over them. No order will be maintained (unlike Sortable), so any draggable element that gets dragged over will be swapped with the source element.
new Swappable(containers: Array[HTMLElement]|NodeList, options: Object): Swappable
To create a swappable instance you need to specify the containers that hold draggable items, e.g.
[document.body] would work too. The second argument is an options object, which is described
below.
swappable.on(eventName: String, listener: Function): Swappable
Swappable uses Draggables event emitter, so you can register callbacks for events. Swappable
also supports method chaining.
swappable.off(eventName: String, listener: Function): Swappable
You can unregister listeners by using .off(), make sure to provide the same callback.
swappable.trigger(eventName: String, event: AbstractEvent): Swappable
You can trigger events through swappable. This is used to fire events internally or by
extensions of Draggable.
droppable.destroy(): void
Detaches all sensors and listeners, and cleans up after itself.
Same as Draggable
| Name | Description | Cancelable | Cancelable action |
|---|---|---|---|
swappable:start | Gets fired when starting to drag | true | Prevents drag |
swappable:swapped | Gets fired before the source gets swapped | true | Prevents swap |
swappable:stop | Gets fired when dragging out of a droppable element | false | - |
Same as Draggable
This sample code will make list items draggable and allows to drop them inside another element:
import {Swappable} from '@shopify/draggable';
const swappable = new Swappable(document.querySelectorAll('ul'), {
draggable: 'li',
});
swappable.on('swappable:start', () => console.log('swappable:start'))
swappable.on('swappable:swapped', () => console.log('swappable:swapped'));
swappable.on('swappable:stop', () => console.log('swappable:stop'));
Draggables ships with two optional plugins: Collidable & Snappable
When you use the collidable plugin you can specify which elements you can't drag over
and it will freeze the mirror movement for you. These currently only work with Sortable, Swappable and Droppable.
collidables {String|Array[HTMLElement]|NodeList|HTMLElement|Function}
A css selector string, an array of elements, a NodeList, a HTMLElement or a function returning elements for collidable
elements.
| Name | Description | Cancelable | Cancelable action |
|---|---|---|---|
collidable:in | Gets fired when dragging near a collidable element | false | - |
collidable:out | Gets fired when dragging away from a collidable element | false | - |
import {Sortable, Collidable} from '@shopify/draggable';
const sortable = new Sortable(document.querySelectorAll('ul'), {
draggable: 'li',
collidables: '.other-list',
plugins: [Collidable]
});
sortable.on('collidable:in', () => console.log('collidable:in'));
sortable.on('collidable:out', () => console.log('collidable:out'));
Snappable simulates a "snap" by hiding the mirror and removing the 'source:dragging' class from the source.
It also sets the 'source:placed' class for potential drop animations.
No options
| Name | Description | Cancelable | Cancelable action |
|---|---|---|---|
snap:in | Gets fired when just before snapping in | true | Prevents snapping |
snap:out | Gets fired when snapping out | false | Prevents snapping out |
import {Sortable, Snappable} from '@shopify/draggable';
const sortable = new Sortable(document.querySelectorAll('ul'), {
draggable: 'li',
plugins: [Snappable]
});
sortable.on('snap:in', () => console.log('snap:in'));
sortable.on('snap:out', () => console.log('snap:out'));
