title: jquery selector including parent id
body: <p>I have a form with 3 select lists, I'm using the jquery multipleSelect addon to select lists using checkboxes, I want to be able to select all selections from a specific group, I can do this for everything on the page using:</p>
  
  <pre><code>    $('input[type=checkbox]')
  </code></pre>
  
  <p>Can I select all checkboxes from a group by including the id of the parent node?</p>
  
  <p>I'm open to other methods of achieving the same.</p>
