I long thought it impossible to have a drop down fall over a flash movie as you would often want in a header of a website.
However, I just saw a website where they accomplished this. After investigating, I found a JQuery library that allows you to do this.
It involves a new way of embedding flash into pages. With just a div tag and a few lines of javascript you can easily embed flash AND have the opportunity to display drop downs over them.
Here’s the link showing it in action:

If you know of any other ways, please pipe up and let us know.
Here’s another link for a great CSS drop down menu:

Update
It turns out that it’s not the awesomeness of jquery tools that allows you to do this. It’s simply a parameter wmode=transparent that allows it. Jquery tools does look really cool, however.
Another good link for CSS menus is http://purecssmenu.com/ It is an online CSS menu generator.
