CDN

To start working with Slick right away, there's a couple of CDN choices available to serve the files as close, and fast as possible to your users:

Example using jsDelivr

Just add a link to the css file in your <head>:

<!-- Add the slick-theme.css if you want default styling -->
<link rel="stylesheet" type="text/css" href="https://cdn.jsdelivr.net/npm/slick-carousel@1.8.1/slick/slick.css"/>
<!-- Add the slick-theme.css if you want default styling -->
<link rel="stylesheet" type="text/css" href="https://cdn.jsdelivr.net/npm/slick-carousel@1.8.1/slick/slick-theme.css"/>

Then, before your closing <body> tag add:

<script type="text/javascript" src="https://cdn.jsdelivr.net/npm/slick-carousel@1.8.1/slick/slick.min.js"></script>

Package Managers

# Bower
bower install --save slick-carousel

# NPM
npm install slick-carousel

Data Attribute Settings

In slick 1.5 you can now add settings using the data-slick attribute. You still need to call $(element).slick() to initialize slick on the element.

Example:

<div data-slick='{"slidesToShow": 4, "slidesToScroll": 4}'>
  <div><h3>1</h3></div>
  <div><h3>2</h3></div>
  <div><h3>3</h3></div>
  <div><h3>4</h3></div>
  <div><h3>5</h3></div>
  <div><h3>6</h3></div>
</div>

Settings

Option	Type	Default	Description
accessibility	boolean	true	Enables tabbing and arrow key navigation. Unless `autoplay: true`, sets browser focus to current slide (or first of current slide set, if multiple `slidesToShow`) after slide change. For full a11y compliance enable focusOnChange in addition to this.

responsive	array	null	Array of objects containing breakpoints and settings objects (see example). Enables settings at given `breakpoint`. Set `settings` to "unslick" instead of an object to disable slick at a given breakpoint.
rows	int	1	Setting this to more than 1 initializes grid mode. Use slidesPerRow to set how many slides should be in each row.

Responsive Option Example

The responsive option, and value, is quite unique and powerful. You can use it like so:

$(".slider").slick({

  // normal options...
  infinite: false,

  // the magic
  responsive: [{

      breakpoint: 1024,
      settings: {
        slidesToShow: 3,
        infinite: true
      }

    }, {

      breakpoint: 600,
      settings: {
        slidesToShow: 2,
        dots: true
      }

    }, {

      breakpoint: 300,
      settings: "unslick" // destroys slick

    }]
});

Events

In slick 1.4, callback methods were deprecated and replaced with events. Use them before the initialization of slick as shown below:

// On swipe event
$('.your-element').on('swipe', function(event, slick, direction){
  console.log(direction);
  // left
});

// On edge hit
$('.your-element').on('edge', function(event, slick, direction){
  console.log('edge was hit')
});

// On before slide change
$('.your-element').on('beforeChange', function(event, slick, currentSlide, nextSlide){
  console.log(nextSlide);
});

Event	Params	Description
afterChange	event, slick, currentSlide	After slide change callback
beforeChange	event, slick, currentSlide, nextSlide	Before slide change callback
breakpoint	event, slick, breakpoint	Fires after a breakpoint is hit
destroy	event, slick	When slider is destroyed, or unslicked.
edge	event, slick, direction	Fires when an edge is overscrolled in non-infinite mode.
init	event, slick	When Slick initializes for the first time callback. Note that this event should be defined before initializing the slider.
reInit	event, slick	Every time Slick (re-)initializes callback
setPosition	event, slick	Every time Slick recalculates position
swipe	event, slick, direction	Fires after swipe/drag
lazyLoaded	event, slick, image, imageSource	Fires after image loads lazily
lazyLoadError	event, slick, image, imageSource	Fires after image fails to load

Methods

Methods are called on slick instances through the slick method itself in version 1.4, see below:

// Add a slide
$('.your-element').slick('slickAdd',"<div></div>");

// Get the current slide
var currentSlide = $('.your-element').slick('slickCurrentSlide');

This new syntax allows you to call any internal slick method as well:

// Manually refresh positioning of slick
$('.your-element').slick('setPosition');

Method	Argument	Description
`slick`	options : object	Initializes Slick
`unslick`		Destroys Slick
`slickNext`		Triggers next slide
`slickPrev`		Triggers previous slide
`slickPause`		Pause Autoplay
`slickPlay`		Start Autoplay (will also set `autoplay` option to `true`)
`slickGoTo`	index : int, dontAnimate : bool	Goes to slide by index, skipping animation if second parameter is set to true
`slickCurrentSlide`		Returns the current slide index
`slickAdd`	element : html or DOM object, index: int, addBefore: bool	Add a slide. If an index is provided, will add at that index, or before if addBefore is set. If no index is provided, add to the end or to the beginning if addBefore is set. Accepts HTML String
`slickRemove`	index: int, removeBefore: bool	Remove slide by index. If removeBefore is set true, remove slide preceding index, or the first slide if no index is specified. If removeBefore is set to false, remove the slide following index, or the last slide if no index is set.
`slickFilter`	filter : selector or function	Filters slides using jQuery .filter syntax
`slickUnfilter`		Removes applied filter
`slickGetOption`	option : string(option name)	Gets an option value.
`slickSetOption`	change an option, `refresh` is always `boolean` and will update UI changes...
`option, value, refresh`	change a single `option` to given `value`; `refresh` is optional.
`"responsive", [{ breakpoint: n, settings: {} }, ... ], refresh`	change or add whole sets of responsive options
`{ option: value, option: value, ... }, refresh`	change multiple `option`s to corresponding `value`s.

Example

Initialize with:

$(element).slick({
  dots: true,
  speed: 500
});

Change the speed with:

$(element).slick('slickSetOption', 'speed', 5000, true);

Destroy with:

$(element).slick('unslick');
