title: IE dropdown menus behind pdf in iframe
body: <p>I'm trying to fix a site where multiple pdfs are pulled into an iframe depending on the menu item you select. This works fine for most browsers but in IE7, 8 and 9 when a pdf is displayed in the iframe the dropdown nav goes behind the iframe.</p>
  
  <p>This is not a z-index problem, I know it's an issue with IE. I also know that I can use google pdf view and all will be well but they don't want to rely on this.</p>
  
  <p>Can anyone offer a suggestion on how to fix this. Is there a plugin I can use?</p>
  
  <p>Thanks</p>
