Usage
Initialize Draggabilly as a jQuery plugin
var $draggable = $('.draggable').draggabilly({
// options...
})
Initialize Draggabilly with vanilla JS
var elem = document.querySelector('.draggable');
var draggie = new Draggabilly( elem, {
// options...
});
// or pass in selector string as first argument
var draggie = new Draggabilly( '.draggable', {
// options...
});
// if you have multiple .draggable elements
// get all draggie elements
var draggableElems = document.querySelectorAll('.draggable');
// array of Draggabillies
var draggies = []
// init Draggabillies
for ( var i=0; i < draggableElems.length; i++ ) {
var draggableElem = draggableElems[i];
var draggie = new Draggabilly( draggableElem, {
// options...
});
draggies.push( draggie );
}
Classes
.is-pointer-down
added when the user's pointer (mouse, touch, pointer) first presses down..is-dragging
added when elements starts to drag.
Options
axis
Type: String
Values: 'x'
or 'y'
axis: 'x'
Constrains movement to horizontal or vertical axis.
containment
Type: Element, Selector String, or Boolean
containment: '.container'
Contains movement to the bounds of the element. If true
, the container will be the parent element.
grid
Type: Array
Values: [ x, y ]
grid: [ 20, 20 ]
Snaps the element to a grid, every x and y pixels.
handle
Type: Selector String, Array, HTMLElement
// select all .handle children with selector string
handle: '.handle'
// set as element
handle: element.querySelector('.handle')
// set as array or NodeList
handle: [ element.querySelector('.handle1'), element.querySelector('.handle2') ]
Specifies on what element the drag interaction starts.
handle
is useful for when you do not want all inner elements to be used for dragging, like inputs and forms. See back handle example on CodePen.
Events
Bind events with jQuery with standard jQuery event methods .on()
, .off()
, and .one()
. Inside jQuery event listeners this
refers to the Draggabilly element.
// jQuery
function listener(/* parameters */) {
// get Draggabilly instance
var draggie = $(this).data('draggabilly');
console.log( 'eventName happened', draggie.position.x, draggie.position.y );
}
// bind event listener
$draggable.on( 'eventName', listener );
// unbind event listener
$draggable.off( 'eventName', listener );
// bind event listener to trigger once. note ONE not ON
$draggable.one( 'eventName', function() {
console.log('eventName happened just once');
});
Bind events with vanilla JS with .on()
, .off()
, and .once()
methods. Inside vanilla JS event listeners this
refers to the Draggabilly instance.
// vanilla JS
function listener(/* parameters */) {
console.log( 'eventName happened', this.position.x, this.position.y );
}
// bind event listener
draggie.on( 'eventName', listener );
// unbind event listener
draggie.off( 'eventName', listener );
// bind event listener to trigger once. note ONCE not ONE or ON
draggie.once( 'eventName', function() {
console.log('eventName happened just once');
});
dragStart
Triggered when dragging starts and the element starts moving. Dragging starts after the user's pointer has moved a couple pixels to allow for clicks.
// jQuery
$draggable.on( 'dragStart', function( event, pointer ) {...})
// vanilla JS
draggie.on( 'dragStart', function( event, pointer ) {...})
event
- Type: Event - the originalmousedown
ortouchstart
eventpointer
- Type: MouseEvent or Touch - the event object that has.pageX
and.pageY
dragMove
Triggered when dragging moves.
// jQuery
$draggable.on( 'dragMove', function( event, pointer, moveVector ) {...})
// vanilla JS
draggie.on( 'dragMove', function( event, pointer, moveVector ) {...})
event
- Type: Event - the originalmousemove
ortouchmove
eventpointer
- Type: MouseEvent or Touch - the event object that has.pageX
and.pageY
moveVector
Type: Object - How far the pointer has moved from its start position{ x: 20, y: -30 }
dragEnd
Triggered when dragging ends.
// jQuery
$draggable.on( 'dragEnd', function( event, pointer ) {...})
// vanilla JS
draggie.on( 'dragEnd', function( event, pointer ) {...})
event
- Type: Event - the originalmouseup
ortouchend
eventpointer
- Type: MouseEvent or Touch - the event object that has.pageX
and.pageY
pointerDown
Triggered when the user's pointer (mouse, touch, pointer) presses down.
// jQuery
$draggable.on( 'pointerDown', function( event, pointer ) {...})
// vanilla JS
draggie.on( 'pointerDown', function( event, pointer ) {...})
event
- Type: Event - the originalmousedown
ortouchstart
eventpointer
- Type: MouseEvent or Touch - the event object that has.pageX
and.pageY
pointerMove
Triggered when the user's pointer moves.
// jQuery
$draggable.on( 'pointerMove', function( event, pointer, moveVector ) {...})
// vanilla JS
draggie.on( 'pointerMove', function( event, pointer, moveVector ) {...})
event
- Type: Event - the originalmousemove
ortouchmove
eventpointer
- Type: MouseEvent or Touch - the event object that has.pageX
and.pageY
moveVector
Type: Object - How far the pointer has moved from its start position{ x: 20, y: -30 }
pointerUp
Triggered when the user's pointer unpresses.
// jQuery
$draggable.on( 'pointerUp', function( event, pointer ) {...})
// vanilla JS
draggie.on( 'pointerUp', function( event, pointer ) {...})
event
- Type: Event - the originalmouseup
ortouchend
eventpointer
- Type: MouseEvent or Touch - the event object that has.pageX
and.pageY
staticClick
Triggered when the user's pointer is pressed and unpressed and has not moved enough to start dragging.
click
events are hard to detect with draggable UI, as they are triggered whenever a user drags. Draggabilly's staticClick event resolves this, as it is triggered when the user has not dragged.
// jQuery
$draggable.on( 'staticClick', function( event, pointer ) {...})
// vanilla JS
draggie.on( 'staticClick', function( event, pointer ) {...})
event
- Type: Event - the originalmouseup
ortouchend
eventpointer
- Type: MouseEvent or Touch - the event object that has.pageX
and.pageY

disable
// jQuery
$draggable.draggabilly('disable')
// vanilla JS
draggie.disable()
enable
// jQuery
$draggable.draggabilly('enable')
// vanilla JS
draggie.enable()
setPosition
// jQuery
$draggable.draggabilly( 'setPosition', x, y )

draggie.dragEnd()
destroy
// jQuery
$draggable.draggabilly('destroy')
// vanilla JS
draggie.destroy()
jQuery.fn.data('draggabilly')
Get the Draggabilly instance from a jQuery object. Draggabilly instances are useful to access Draggabilly properties.
var draggie = $('.draggable').data('draggabilly')
// access Draggabilly properties
console.log( 'draggie at ' + draggie.position.x + ', ' + draggie.position.y )
Properties
position
draggie.position
// => { x: 20, y: -30 }
position
- Type: Objectx
- Type: Numbery
- Type: Number
Module loaders
Webpack & Browserify
Install Draggabilly with npm.
npm install draggabilly
var Draggabilly = require('draggabilly');
var draggie = new Draggabilly( '.draggable', {

To use Draggabilly as a jQuery plugin, you need to install and call jQuery Bridget.
npm install jquery-bridget
var $ = require('jquery');
var jQueryBridget = require('jquery-bridget');
var Draggabilly = require('draggabilly');
// make Draggabilly a jQuery plugin
jQueryBridget( 'draggabilly', Draggabilly, $ );
// now you can use $().draggabilly()
$('.draggable').draggabilly({...})
