title: Select dropdown box z-index issue on modal window
body: <p>I have the below dropdown that I have linked to a image map modal window with an link.  However the selection list is on top of the modal window even though the modal is set to <code>z-index: 99999;</code></p>
  
  <p>Any thoughts on how to get the selection box to not overlay the modal window?  Can I set the z-index of the selection list somehow?</p>
