Multi select drop down in Wicket - wicket

Question

How to implement multiple select drop down in Wicket. I am able to create multi select drop down view using bootstrap but I am not able to get how to relate selected options with IModel of drop down component? Is there any possibility in Wicket? I do not want to use ListMultipleChoice.

Here is a sample code.
{
private IModel<List<? extends String>> statusChoices;
private DropDownChoice<String> status;
private String statusFilter = "firstChoice";
// List of Items in drop down
statusChoices = new AbstractReadOnlyModel<List<? extends String>>() {
#Override
public List<String> getObject() {
List<String> list = new ArrayList<String>();
list.add("firstChoice");
list.add("secondChoice");
list.add("thirdChoice");
return list;
}
};
status = new DropDownChoice<String>("status",new PropertyModel<String>(this, "statusFilter"), statusChoices);
status.add(new AjaxFormComponentUpdatingBehavior("onchange") {
#Override
protected void onUpdate(AjaxRequestTarget target) {
if(statusFilter.equals("firstChoice"))
// Do Somthing
else
// Do Somthing
}
});
}
