Slider

To add a slider widget to your page, use a standard input with the type="range" attribute. The input's value is used to configure the starting position of the handle and the value is populated in the text input. Specify min and max attribute values to set the slider's range. If you want to constrain input to specific increments, add the step attribute. Set the value attribute to define the initial value. The framework will parse these attributes to configure the slider widget.

As you drag the slider's handle, the framework will update the native input's value (and vice-versa) so they are always in sync; this ensures that the value is submitted with the form.

Set the for attribute of the label to match the id of the input so they are semantically associated. It's possible to accessibly hide the label if it's not desired in the page layout, but we require that it is present in the markup for semantic and accessibility reasons.

The framework will find all input elements with a type="range" and automatically enhance them into a slider with an accompanying input without any need to apply a data-role attribute. To prevent the automatic enhancement of this input into a slider, add data-role="none" attribute to the input and wrap them in a div with the data-role="fieldcontain" attribute to group them.

In this example, the acceptable range is 0-100.

1
2
 
<label for="slider-1">Input slider:</label>
<input type="range" name="slider-1" id="slider-1" value="60" min="0" max="100">

The default slider with these settings is displayed like this:

Step increment

To force the slider to snap to a specific increment, add the step attribute to the input. By default, the step is 1, but in this example, the step is 10 and the maximum value is 500.

In this example, the acceptable range is 0-100.

1
2
 
<label for="slider-1">Input slider:</label>
<input type="range" name="slider-1" id="slider-1" value="60" min="0" max="100" step="10">

This will produce an input that snaps to increments of 50. If a value is added to the input that isn't valid with the step increment, the value will be reset on blur to the closest step.

Fill highlight

To have a highlight fill on the track up to the slider handle position, add the data-highlight="true" attribute to the input. The fill uses active state swatch.

1
2
 
<label for="slider-fill">Input slider:</label>
<input type="range" name="slider-fill" id="slider-fill" value="60" min="0" max="100" data-highlight="true">

Mini version

For a more compact version that is useful in toolbars and tight spaces, add the data-mini="true" attribute to the element to create a mini version.

1
2
 
<label for="slider-mini">Input slider:</label>
<input type="range" name="slider-mini" id="slider-mini" value="25" min="0" max="100" data-highlight="true" data-mini="true">

This will produce a slider and its corresponding input that are not as tall as the standard version. The input also has a smaller text size.

Field containers

Optionally wrap the slider markup in a container with the data-role="fieldcontain" attribute to help visually group it in a longer form. In this example, the step attribute is omitted to allow any whole number value to be selected.

<div data-role="fieldcontain">
  <label for="slider-2">Input slider:</label>
  <input type="range" name="slider-2" id="slider-2" value="25" min="0" max="100">
</div>

The slider is now displayed like this:

Sliders also respond to key commands. Right Arrow, Up Arrow and Page Up keys increase the value; Left Arrow, Down Arrow and Page Down keys decrease it. To move the slider to its minimum or maximum value, use the Home or End key, respectively.

Calling the slider plugin

This plugin will auto initialize on any page that contains a text input with the type="range" attribute. However, if needed you can directly call the slider plugin on any selector, just like any jQuery plugin:

1
 
$( "input" ).slider();

Theming the slider

To set the theme swatch for the slider, add a data-theme attribute to the input which will apply the theme to both the input, handle and track. The track swatch can be set separately by adding the data-track-theme attribute to apply the down state version of the selected button swatch.

<div data-role="fieldcontain">
  <label for="slider-3">Input slider:</label>
  <input type="range" name="slider-3" id="slider-3" value="25" min="0" max="100" data-theme="a" data-track-theme="b">
</div>

This will produce a themed slider:

Flip Toggle Switch

A binary "flip" switch is a common UI element on mobile devices that is used for binary on/off or true/false data input. You can either drag the flip handle like a slider or tap one side of the switch.

To create a flip toggle, start with a select with two options. The first option will be styled as the "off" state switch and the second will be styled as the "on" state so write your options accordingly.

Set the for attribute of the label to match the id of the input so they are semantically associated. It's possible to accessibly hide the label if it's not desired in the page layout, but we require that it is present in the markup for semantic and accessibility reasons.

<label for="flip-1">Flip switch:</label>
<select name="flip-1" id="flip-1" data-role="slider">
  <option value="off">Off</option>
  <option value="on">On</option>
</select>

This will produce a basic flip toggle switch input. The default styles set the width of the switch to 100% of the parent container and stack the label on a separate line.

Longer Labels

The control is proportionally scaled, so to use longer labels one can just add a line of CSS setting the switch to the desired width. For example, given the following markup:

1
2
3
4
5
6
7
 
<div class="containing-element">
  <label for="flip-min">Flip switch:</label>
  <select name="flip-min" id="flip-min" data-role="slider">
    <option value="off">Switch Off</option>
    <option value="on">Switch On</option>
  </select>
</div>

.containing-element .ui-slider-switch { width: 9em } will produce:

As some default styles hinge on fieldcontains, note that you may have to ensure that custom styles apply to switches within fieldcontains by using .ui-field-contain div.ui-slider-switch { width: […]; }.

Mini version

For a more compact version that is useful in toolbars and tight spaces, add the data-mini="true" attribute to the element to create a mini version.

1
2
3
4
5
 
<label for="flip-mini">Flip switch:</label>
<select name="flip-mini" id="flip-mini" data-role="slider" data-mini="true">
  <option value="off">Off</option>
  <option value="on">On</option>
</select>

This will produce a flip switch that is not as tall as the standard version and has a smaller text size.

Field containers

Optionally wrap the switch markup in a container with the data-role="fieldcontain" attribute to help visually group it in a longer form. In this example, the step attribute is omitted to allow any whole number value to be selected.

<div data-role="fieldcontain">
  <label for="flip-2">Flip switch:</label>
  <select name="flip-2" id="flip-2" data-role="slider" data-mini="true">
    <option value="off">Off</option>
    <option value="on">On</option>
  </select>
</div>

The flip toggle switch is now displayed like this:

Theming the flip switch

Like all form elements, this widget will automatically inherit the theme from its parent container. To choose a specific theme color swatch, specify the data-theme attribute on the select and specify a swatch letter.

<div data-role="fieldcontain">
  <label for="flip-3">Flip switch:</label>
  <select name="flip-3" id="flip-3" data-role="slider" data-theme="a">
    <option value="no">No</option>
    <option value="yes">Yes</option>
  </select>
</div>

This results in a switch with the swatch "a" colors for the handle. Note that the lefthand "on" state gets the active state color.

Here is a swatch "e" variation:

It is also possible to theme the track of the flip switch by adding the data-track-theme attribute and specifying the chosen swatch letter on the select.

Here's an example of a flip switch with the swatch "a" applied to the track and swatch "c" applied to the handle:

1

<div data-role="fieldcontain">
  <label for="flip-5">Flip switch:</label>
  <select name="flip-5" id="flip-5" data-role="slider" data-theme="c" data-track-theme="a">
    <option value="no">No</option>
    <option value="yes">Yes</option>
  </select>
</div>

Calling the switch plugin

This plugin will auto initialize on any page that contains a text input with the type="slider" attribute. However, if needed you can directly call the slider plugin on any selector, just like any jQuery plugin:

1
 
$( "input" ).slider();

    <option value="yes">Yes</option>
  </select>
</div>
