Radio buttons

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 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.

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.

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.

Because radio buttons use the label element for the text displayed next to the checkbox form element, we recommend wrapping 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-1" id="radio-choice-1" value="choice-1" checked="checked" />
     	<label for="radio-choice-1">Cat</label>

     	<input type="radio" name="radio-choice-1" id="radio-choice-2" value="choice-2"  />
     	<label for="radio-choice-2">Dog</label>

     	<input type="radio" name="radio-choice-1" id="radio-choice-3" value="choice-3"  />
     	<label for="radio-choice-3">Hamster</label>

     	<input type="radio" name="radio-choice-1" 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 label on a separate line.

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

         	<input type="radio" name="radio-choice-1" id="radio-choice-2" value="choice-2"  />
         	<label for="radio-choice-2">Dog</label>

         	<input type="radio" name="radio-choice-1" id="radio-choice-3" value="choice-3"  />
         	<label for="radio-choice-3">Hamster</label>

         	<input type="radio" name="radio-choice-1" id="radio-choice-4" value="choice-4"  />
         	<label for="radio-choice-4">Lizard</label>
    </fieldset>
</div>

Horizontal radio button sets

Radio buttons can also be used for grouped button sets 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:

The framework will float the labels so they sit side-by-side on a line, hides the radio button icons and only round the left and right edges of the group.
