This handy lil slider is perfect for setting specific values within a range.


Create a slider by adding the class .slider and the attribute data-slider to a container element. You should also define both a starting and maximum value for the slider.

Inside the container are three elements:

  • The handle (.slider-handle), which the user drags.
  • The fill (.slider-fill), which resizes dynamically based on where the handle is.
  • A hidden <input>, which is where the value of the slider is stored.
<div class="slider" data-slider data-initial-start="50" data-end="200">
  <span class="slider-handle"  data-slider-handle role="slider" tabindex="1"></span>
  <span class="slider-fill" data-slider-fill></span>
  <input type="hidden">


To get vertical, just add a .vertical class and data-vertical="true" the slider.

<div class="slider vertical" data-slider data-initial-start="25" data-end="200" data-vertical="true">
  <span class="slider-handle" data-slider-handle role="slider" tabindex="1"></span>
  <span class="slider-fill" data-slider-fill></span>
  <input type="hidden">


Add the class .disabled to disable interaction with the slider.

<div class="slider disabled" data-slider data-initial-start="78">
  <span class="slider-handle" data-slider-handle role="slider" tabindex="1"></span>
  <span class="slider-fill" data-slider-fill></span>
  <input type="hidden">

Two Handles

Two-handle sliders can be used to define a range of values, versus a single value. To make a two-handle slider, add a second handle, and a second <input>. This works with horizontal and vertical sliders.

You can add IDs to the <input>s inside the sliders to make it easier to access the values. If you don't, the plugin will add an ID to each for you.

Note that the first handle manipulates the first <input>, while the second handle manipulates the second <input>.

<div class="slider" data-slider data-initial-start="25" data-initial-end="75">
  <span class="slider-handle" data-slider-handle role="slider" tabindex="1"></span>
  <span class="slider-fill" data-slider-fill></span>
  <span class="slider-handle" data-slider-handle role="slider" tabindex="1"></span>
  <input type="hidden">
  <input type="hidden">

Data Binding

Data binding allows you to connect the slider to an external <input> field. With data binding set up, dragging the handle will change the value inside the text field, and editing the number in the text field will move the slider in real-time.

To set it all up, create an <input> with an ID and add aria-controls="id" to the slider handle, where id is the ID of the <input>.

<div class="small-10 columns">
  <div class="slider" data-slider data-initial-start="50">
    <span class="slider-handle"  data-slider-handle role="slider" tabindex="1" aria-controls="sliderOutput1"></span>
    <span class="slider-fill" data-slider-fill></span>
<div class="small-2 columns">
  <input type="number" id="sliderOutput1">

Or with a step size:

<div class="small-10 columns">
  <div class="slider" data-slider data-initial-start="50" data-step="5">
    <span class="slider-handle"  data-slider-handle role="slider" tabindex="1" aria-controls="sliderOutput2"></span>
    <span class="slider-fill" data-slider-fill></span>
<div class="small-2 columns">
  <input type="number" id="sliderOutput2">

Native Range Slider

In Foundation 6.2, we introduced styles for <input type="range">, the native HTML element for range sliders. It's not supported in every browser, namely IE9 and some older mobile browsers. View browser support for the range input type.

<input type="range" min="1" max="100" step="1">

If you're using the Sass version of Foundation, add this line to your main Sass file:

@include foundation-range-input;

It's possible to use both the JavaScript slider and the native slider in the same codebase, as the CSS selectors used don't overlap. Here's what's different about the native slider:

  • Less markup: just write <input type="range"> and you're good.
  • No JavaScript is needed, which guarantees it runs faster in most browsers.
  • To disable the slider, add disabled as an attribute, instead of a class.
  • No support for vertical orientation.
  • No support for two handles.

Non-linear value translation

Sometimes not every value is of equal importance. In the example below, the slider focusses on the higher numbers by adding a log-type position value funtion. Alternatively there is also a pow-type position value function available, making the reverse possible.

<div class="small-10 columns">
<div class="slider" data-slider data-initial-start="50" data-step="1" data-position-value-function="log" data-non-linear-base="5">
  <span class="slider-handle" data-slider-handle role="slider" tabindex="1" aria-controls="sliderOutputNonLinear"></span>
<div class="small-2 columns">
  <input type="number" id="sliderOutputNonLinear">

The nonLinearBase-option is optional and defaults to 5.


The slider takes into account the width of the handles when calculating how to display itself. This means that if the slider is initially hidden, or hidden while the value is adjusted, the resulting visual will be slightly different because the width of the handle is indeterminate. If this is problematic, you can use JavaScript to cause the slider to reflow at the time that you change it from being hidden. Example:


Sass Reference


The default styles of this component can be customized using these Sass variables in your project's settings file.

NameTypeDefault ValueDescription
$slider-width-vertical Number 0.5rem

Default slider width of a vertical slider. (Doesn't apply to the native slider.)

$slider-transition Transition all 0.2s ease-in-out

Transition properties to apply to the slider handle and fill. (Doesn't apply to the native slider.)


We use these mixins to build the final CSS output of this component. You can use the mixins yourself to build your own class structure out of our components.


@include slider-container;

Adds the general styles for sliders.


@include slider-fill;

Adds the general styles for active fill for sliders.


@include slider-handle;

Adds the general styles for the slider handles.

JavaScript Reference


The file foundation.slider.js must be included in your JavaScript to use this plugin, along with foundation.core.js. This plugin also requires these utility libraries:

  • foundation.util.motion.js
  • foundation.util.triggers.js
  • foundation.util.keyboard.js
  • foundation.util.touch.js


Creates a new instance of a slider control.

var elem = new Foundation.Slider(element, options);
element jQuery jQuery object to make into a slider control.
options Object Overrides to the default plugin settings.

Plugin Options

Use these options to customize an instance of Slider. Plugin options can be set as individual data attributes, one combined data-options attribute, or as an object passed to the plugin's constructor. Learn more about how JavaScript plugins are initialized.

Name Type Default Description
data-start number 0 Minimum value for the slider scale.
data-end number 100 Maximum value for the slider scale.
data-step number 1 Minimum value change per change event.
data-initial-start number 0 Value at which the handle/input *(left handle/first input)* should be set to on initialization.
data-initial-end number 100 Value at which the right handle/second input should be set to on initialization.
data-binding boolean false Allows the input to be located outside the container and visible. Set to by the JS
data-click-select boolean true Allows the user to click/tap on the slider bar to select a value.
data-vertical boolean false Set to true and use the `vertical` class to change alignment to vertical.
data-draggable boolean true Allows the user to drag the slider handle(s) to select a value.
data-disabled boolean false Disables the slider and prevents event listeners from being applied. Double checked by JS with `disabledClass`.
data-double-sided boolean false Allows the use of two handles. Double checked by the JS. Changes some logic handling.
data-decimal number 2 Number of decimal places the plugin should go to for floating point precision.
data-move-time number 200 Time, in ms, to animate the movement of a slider handle if user clicks/taps on the bar. Needs to be manually set if updating the transition time in the Sass settings.
data-disabled-class string disabled Class applied to disabled sliders.
data-invert-vertical boolean false Will invert the default layout for a vertical slider.
data-changed-delay number 500 Milliseconds before the `changed.zf-slider` event is triggered after value change.
data-non-linear-base number 5 Basevalue for non-linear sliders
data-position-value-function string linear Basevalue for non-linear sliders, possible values are: `'linear'`, `'pow'` & `'log'`. Pow and Log use the nonLinearBase setting.


These events will fire from any element with a Slider plugin attached.

moved.zf.slider Fires when the handle is done moving.
changed.zf.slider Fires when the value has not been change for a given time.
