public class RadioChoice<T>
extends AbstractSingleSelectChoice<T>

A choice subclass that shows choices in radio style.

Java:

 List SITES = Arrays.asList(new String[] { "The Server Side", "Java Lobby", "Java.Net" });
 // Add a radio choice component that uses Input's 'site' property to designate the
 // current selection, and that uses the SITES list for the available options.
 form.add(new RadioChoice("site", SITES));
 

HTML:

    <span style="vertical-align: top;" wicket:id="site">
        <input type="radio">site 1</input>
        <input type="radio">site 2</input>
    </span>
