Drop down menu over top of html

the image explains it best:

i have a 40px menu bar. the menu is going to be in flash, and have drop downs and i need the drop downs to extend beyond the 40px of the green bar, over top of html (and SiFR) content.

i’m pretty sure this is an embedding and/or issue. if i set the movie height in flash to 300px, setting the height to 300 when i embed it will force all the html content down 260px and make a huge gap od white space. if i assign the heights to 40 in flash and when i embed it, i’m pretty sure it’ll just cut everything off at 40.

any help?
