CDN

To start working with Slick right away, there's a couple of CDN choices availabile 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="//cdn.jsdelivr.net/gh/kenwheeler/[email protected]/slick/slick.css"/>
<!-- Add the slick-theme.css if you want default styling -->
<link rel="stylesheet" type="text/css" href="//cdn.jsdelivr.net/gh/kenwheeler/[email protected]/slick/slick-theme.css"/>

Then, before your closing <body> tag add:

<script type="text/javascript" src="//cdn.jsdelivr.net/gh/kenwheeler/[email protected]/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. adaptiveHeight boolean false Adapts slider height to the current slide appendArrows string $(element) Change where the navigation arrows are attached (Selector, htmlString, Array, Element, jQuery object) appendDots string $(element) Change where the navigation dots are attached (Selector, htmlString, Array, Element, jQuery object) arrows boolean true Enable Next/Prev arrows asNavFor string $(element) Enables syncing of multiple sliders autoplay boolean false Enables auto play of slides autoplaySpeed int 3000 Auto play change interval centerMode boolean false Enables centered view with partial prev/next slides. Use with odd numbered slidesToShow counts. centerPadding string '50px' Side padding when in center mode. (px or %) cssEase string 'ease' CSS3 easing customPaging function n/a Custom paging templates. See source for use example. dots boolean false Current slide indicator dots dotsClass string 'slick-dots' Class for slide indicator dots container draggable boolean true Enables desktop dragging easing string 'linear' animate() fallback easing edgeFriction integer 0.15 Resistance when swiping edges of non-infinite carousels fade boolean false Enables fade focusOnSelect boolean false Enable focus on selected element (click) focusOnChange boolean false Puts focus on slide after change infinite boolean true Infinite looping initialSlide integer 0 Slide to start on lazyLoad string 'ondemand' Accepts 'ondemand' or 'progressive' for lazy load technique. 'ondemand' will load the image as soon as you slide to it, 'progressive' loads one image after the other when the page loads. mobileFirst boolean false Responsive settings use mobile first calculation nextArrow string (html | jQuery selector) | object (DOM node | jQuery object) <button type="button" class="slick-next">Next</button> Allows you to select a node or customize the HTML for the "Next" arrow. pauseOnDotsHover boolean false Pauses autoplay when a dot is hovered pauseOnFocus boolean true Pauses autoplay when slider is focussed pauseOnHover boolean true Pauses autoplay on hover prevArrow string (html | jQuery selector) | object (DOM node | jQuery object) <button type="button" class="slick-prev">Previous</button> Allows you to select a node or customize the HTML for the "Previous" arrow. respondTo string 'window' Width that responsive object responds to. Can be 'window', 'slider' or 'min' (the smaller of the two). 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. rtl boolean false Change the slider's direction to become right-to-left slide string '' Slide element query slidesPerRow int 1 With grid mode initialized via the rows option, this sets how many slides are in each grid row. slidesToScroll int 1 # of slides to scroll at a time slidesToShow int 1 # of slides to show at a time speed int 300 Transition speed swipe boolean true Enables touch swipe swipeToSlide boolean false Swipe to slide irrespective of slidesToScroll touchMove boolean true Enables slide moving with touch touchThreshold int 5 To advance slides, the user must swipe a length of (1/touchThreshold) * the width of the slider. useCSS boolean true Enable/Disable CSS Transitions useTransform boolean true Enable/Disable CSS Transforms variableWidth boolean false Disables automatic slide width calculation vertical boolean false Vertical slide direction verticalSwiping boolean false Changes swipe direction to vertical waitForAnimate boolean true Ignores requests to advance the slide while animating zIndex number 1000 Set the zIndex values for slides, useful for IE9 and lower
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 options to corresponding values.

Example

Initialize with:

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

Change the speed with:

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

Destroy with:

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