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:
- ```html
- <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.

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

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) | `` | 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) | `` | 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 givenbreakpoint. 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.

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

Responsive Option Example
The responsive option, and value, is quite unique and powerful.
You can use it like so:
- ```javascript
- $(".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:
- ```javascript
- // 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:
- ```javascript
- // 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:
- ```javascript
- // 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 || Object
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](https://github.com/kenwheeler/slick#settings) 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](https://github.com/kenwheeler/slick#settings) to corresponding values.
Example
Initialize with:
- ```javascript
- $(element).slick({
- dots: true,
- speed: 500
- });
- ```
- Change the speed with:
- ```javascript
$(element).slick('slickSetOption', 'speed', 5000, true);
- ```
- Destroy with:
