<p>To add a slider widget to your page, use a standard <code>input</code> with the <code>type="range"</code> attribute. The input's <code>value</code> is used to configure the starting position of the handle and the value is populated in the text input. Specify <code>min</code> and <code>max</code> attribute values to set the slider's range. If you want to constrain input to specific increments, add the <code>step</code> attribute. Set the <code>value</code> attribute to define the initial value. The framework will parse these attributes to configure the slider widget. View the <a href="../../api/data-attributes.html">data- attribute reference</a> to see all the possible attributes you can add to sliders.</p>
<p>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.</p>
<p>Set the <code>for</code> attribute of the <code>label</code> to match the <code>id</code> of the <code>input</code> so they are semantically associated. It's possible to <a href="../docs-forms.html">accessibly hide the label</a> if it's not desired in the page layout, but we require that it is present in the markup for semantic and accessibility reasons.</p>
<p>The framework will find all <code>input</code> elements with a <code>type="range"</code> and automatically enhance them into a slider with an accompanying input without any need to apply a <code>data-role</code> attribute. To prevent the automatic enhancement of this input into a slider, add <code>data-role="none"</code> attribute to the <code>input</code> and wrap them in a <code>div</code> with the <code> data-role="fieldcontain"</code> attribute to group them. In this example, the acceptable range is 0-100. </p>
<pre><code>
<label for="slider-1">Input slider:</label>
<input type="range" name="slider-1" id="slider-1" value="60" min="0" max="100" />
</code></pre>
<p>The default slider with these settings is displayed like this:</p>
<label for="slider-1">Input slider:</label>
<input type="range" name="slider-1" id="slider-1" value="60" min="0" max="100" />
<h2>Step increment</h2>
<p>To force the slider to snap to a specific increment, add the <code>step</code> attribute to the input. By default, the step is 1, but in this example, the step is 50 and the maximum value is 500.</p>
<pre><code>
<label for="slider-step">Input slider:</label>
<input type="range" name="slider-step" id="slider-step" value="150" min="0" max="500" <strong>step="50"</strong> />
</code></pre>
<p>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.</p>
<label for="slider-step">Input slider:</label>
<input type="range" name="slider-step" id="slider-step" value="150" min="0" max="500" step="50" />
<h2>Fill highlight</h2>
<p>To have a highlight fill on the track up to the slider handle position, add the <code>data-highlight="true"</code> attribute to the input. The fill uses the active state swatch. </p>
<pre><code>
<label for="slider-fill">Input slider:</label>
<input type="range" name="slider-fill" id="slider-fill" value="60" min="0" max="100" <strong>data-highlight="true"</strong> />
</code></pre>
<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" />
<h2>Mini version</h2>
<p>For a more compact version that is useful in toolbars and tight spaces, add the <code>data-mini="true"</code> attribute to the element to create a <a href="../forms-all-mini.html">mini version</a>. </p>
<pre><code>
<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" <strong>data-mini="true"</strong> />
</code></pre>
<p>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.</p>
<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" />
<h2>Field containers</h2>
<p>Optionally wrap the slider markup in a container with the <code>data-role="fieldcontain"</code> attribute to help visually group it in a longer form. In this example, the <code>step</code> attribute is omitted to allow any whole number value to be selected.</p>
<pre><code>
<strong><div data-role="fieldcontain">
</strong> <label for="slider-2">Input slider:</label>
<input type="range" name="slider-2" id="slider-2" value="25" min="0" max="100" />
<strong></div>
</strong></code></pre>
<p>The slider is now displayed like this:</p>
<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>
<p>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.</p>
<h2>Calling the slider plugin</h2>
<p>This plugin will auto initialize on any page that contains a text <code>input</code> with the <code>type="range"</code> attribute. However, if needed you can directly call the <code>slider</code> plugin on any selector, just like any jQuery plugin:</p>
<pre><code>
$('input').slider();
</code></pre>
<h2>Theming the slider</h2>
<p>To set the theme swatch for the slider, add a <code>data-theme</code> attribute to the <code>input</code> which will apply the theme to both the input, handle and track. The track swatch can be set separately by adding the <code>data-track-theme</code> attribute to apply the down state version of the selected button swatch.</p>
<pre><code>
<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" <strong>data-theme="a" data-track-theme="b"</strong> />
</div>
</code></pre>
<p>This will produce a themed slider:</p>
<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>
</form>
