## Radio buttons

Radio buttons are used to provide a list of options where only a single item can be selected. Traditional desktop radio buttons are not optimized for touch input so jQuery Mobile styles the `label` 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.

The radio 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 data- attribute reference to see all the possible attributes you can add to radio buttons.

## Vertically grouped radio buttons

To create a set of radio buttons, add an `input` with a `type="radio"` attribute and a corresponding `label`. Set the `for` attribute of the `label` to match the `id` of the `input` so they are semantically associated.

The `label` element is displayed next to the radio form element. Wrap the radio buttons in a `fieldset` element that has a `legend` which acts as the title for the question.

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 `data-role="controlgroup"` attribute on the container.

    <fieldset data-role="controlgroup">
    	<legend>Choose a pet:</legend>
         	<input type="radio" name="radio-choice" id="radio-choice-1" value="choice-1" checked="checked" />
         	<label for="radio-choice-1">Cat</label>

         	<input type="radio" name="radio-choice" id="radio-choice-2" value="choice-2"  />
         	<label for="radio-choice-2">Dog</label>

         	<input type="radio" name="radio-choice" id="radio-choice-3" value="choice-3"  />
         	<label for="radio-choice-3">Hamster</label>

         	<input type="radio" name="radio-choice" id="radio-choice-4" value="choice-4"  />
         	<label for="radio-choice-4">Lizard</label>
    </fieldset>

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 legend on a separate line.

## 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.

    <fieldset data-role="controlgroup" data-mini="true">
        	<input type="radio" name="radio-mini" id="radio-mini-1" value="choice-1" checked="checked" />
        	<label for="radio-mini-1">Credit</label>

    	<input type="radio" name="radio-mini" id="radio-mini-2" value="choice-2"  />
        	<label for="radio-mini-2">Debit</label>

        	<input type="radio" name="radio-mini" id="radio-mini-3" value="choice-3"  />
        	<label for="radio-mini-3">Cash</label>
    </fieldset>

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

## Field containers

Optionally wrap the radiobuttons in a container with the `data-role="fieldcontain"` attribute to help visually group it in a longer form.

    <div data-role="fieldcontain">
        <fieldset data-role="controlgroup">
        	<legend>Choose a pet:</legend>
             	<input type="radio" name="radio-choice-2" id="radio-choice-21" value="choice-1" checked="checked" />
             	<label for="radio-choice-21">Cat</label>

             	<input type="radio" name="radio-choice-2" id="radio-choice-22" value="choice-2"  />
             	<label for="radio-choice-22">Dog</label>

             	<input type="radio" name="radio-choice-2" id="radio-choice-23" value="choice-3"  />
             	<label for="radio-choice-23">Hamster</label>

             	<input type="radio" name="radio-choice-2" id="radio-choice-24" value="choice-4"  />
             	<label for="radio-choice-24">Lizard</label>
        </fieldset>
    </div>

## Horizontal radio button sets

Radio buttons can also be used for grouped button sets where only a single button can be selected at once, such as a view switcher control. To make a horizontal radio button set, add the `data-type="horizontal"` to the `fieldset`.

`<fieldset data-role="controlgroup" data-type="horizontal" >`
Layout view: List Grid Gallery

The labels float so they sit side-by-side on a line. The radio button icons are hidden and only the left and right edges of the group are rounded.
