<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. 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>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 ID 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, no 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.</p>

<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.</p>
