public class DropDownChoice<T> extends AbstractSingleSelectChoice<T>
A choice implemented as a dropdown menu/list.

Java: 

 List SITES = Arrays.asList(new String[] { "The Server Side", "Java Lobby", "Java.Net" });
 
 // Add a dropdown choice component that uses Input's 'site' property to designate the
 // current selection, and that uses the SITES list for the available options.
 // Note that when the selection is null, Wicket will lookup a localized string to
 // represent this null with key: "id + '.null'". In this case, this is 'site.null'
 // which can be found in DropDownChoicePage.properties
 form.add(new DropDownChoice("site", SITES));
HTML: 
        <select wicket:id="site">
                <option>site 1</option>
                <option>site 2</option>
        </select>
