How to cover an IE windowed control...

Finally Joe King share a good trick for every developers, including myself, who fought with this annoyning IE behaviour.

If you try to have a DHTML layer over a dropdown list for example, the dropdown controls come always on the top.

Very frustrating with dynamic menus ! I used to push my dropdown controls further down in the page, but if you need a cleaner solution than just hiding the control on a mouseover event, read the full solution on Dotnetjunkies.
