title: make drop down list item unselectable
body: <p>I have a dropdownlist which has several options for generating reports. Based on the type of account the user has certain options which should  be visible but not selectable (as an incentive for them to upgrade).</p>
  
  <p>I was wondering if anyone knew of a way to accomplish this.</p>
  
  <p>The permissions are already in place i just need assistance with making certain items unselectable.</p>
  
  <p>Any help would be much appreciated.</p>
