public class CheckBoxMultipleChoice
extends ListMultipleChoice

A choice subclass that shows choices via checkboxes.

Java:

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

HTML:

    <span valign="top" wicket:id="site">
        <input type="checkbox">site 1</input>
        <input type="checkbox">site 2</input>
    </span>
