I have some page content in an iframe. I also have a drop-down menu that contains some user options. In IE (9), when I open the drop-down the menu, it appears behind the iframe. In every other browser, the behaviour as is correct (the menu appears on top of the iframe).
I have tried applying various z-index properties to these elements without success. Their common parent element is just a <body>
tag.
How can I ensure that the drop-down always appears on top of the iframe in IE?
