A CheckBoxGroup and CheckBoxComponnet components let users select multiple values from a group of checkboxes. These components are more flexible then the CheckBoxMultipleChoice component in that individual checkboxes are full components, unlike with CheckBoxMultipleChoice, and thus can be used anywhere in the markup.
<form wicket:id="form">
<span wicket:id="group">
<input type="checkbox" wicket:id="groupselector">check/uncheck all</input>
<tr wicket:id="persons">
<td><input type="checkbox" wicket:id="checkbox"/></td>
<td><span wicket:id="name">[this is where name will be]</span></td>
<td><span wicket:id="lastName">[this is where lastname will be]</span></td>
</tr>
</span>
</form>
Form f=new Form("form");
