  35     </ul>
  36
  37                 <p>Radio buttons are used to provide a list of options where only a single items can be selected. Traditional desktop radio buttons are not optimized for touch input so in jQuery Mobile, we style the <code>label</code> for the radio buttons so they are larger and look clickable. A custom set of icons are added to the label to provide additional visual feedback.</p>
  38
  39                 <p>Both the radio and checkbox controls below use standard input/label markup, but are styled to be more touch-friendly. The styled control you see is actually the label element, which sits over the real input, so if images fail to load, you'll still have a functional control. In most browsers, clicking the label automatically triggers a click on the input, but we've had to trigger the update manually for a few mobile browsers that don't do this natively. On the desktop, these controls are keyboard and screen-reader accessible. View the <a href="../../api/data-attributes.html">data- attribute reference</a> to see all the possible attributes you can add to radio buttons.</p>
  40
  41                 <h2>Vertically grouped radio buttons</h2>
  42
  43                 <p>To create a set of radio buttons, add an <code>input</code> with a <code>type="radio"</code> attribute and a corresponding <code>label</code>. 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.</p>
  44
  45                 <p>Because radio buttons use the <code>label</code> element for the text displayed next to the checkbox form element, we recommend wrapping the radio buttons in a <code>fieldset</code> element that has a <code>legend</code> which acts as the title for the question.</p>
  46
  47                 <p>To visually integrate multiple radio buttons into a vertically grouped button set, the framework will automatically remove all margins between buttons and round only the top and bottom corners of the set if there is a <code> data-role="controlgroup"</code> attribute on the container.</p>

  67                 <p>This will produce a vertically grouped radio button set. The default styles set the width of the button group to 100% of the parent container and stacks the label on a separate line.</p>
