this doesn't belong to the menu at the top with the flyout!!!
On my site I have played around with many different menus.
this javascript belongs to the drop-down-menu at the bottom, where a 
breadcrumb-like menu with dropdowns for each level appears.

also there is a left menu with counters 
and a menu to jump to neighbor-pages

the flyout at all can also be done with javascript.
I just want to say: you don't need javascript as CSS can switch 
visibility using ':hover'.
as it reads in the CSS http://www.pi-phi.de/t3v4/fileadmin/css/fmenu.css 
at the end:
/* The magic - set to work for up to a 3 level menu, but can be increased 
unlimited */
#nav ul, 
#nav li:hover ul, 
#nav li:hover ul ul, 
[...]
{ display: none; }
#nav li:hover ul, 
#nav ul li:hover ul, 
[...]
{ display: block; }

alpha transparency means two colors are blended and is done with PNG. 
either png8 or png24. 
http://en.wikipedia.org/wiki/Alpha_compositing

with GIF you only can have full transparency for single pixels (or none).
if you want to have a menu where the background is seen through with GIF 
you must use a dither-pattern (http://en.wikipedia.org/wiki/
Dither#Digital_photography_and_image_processing) which will lead to moire-
patterns (http://en.wikipedia.org/wiki/Moire) (as you can see on some 
windows-version when you shutdown.)

better is alpha-transparency with PNG. any version you like.
but IE6 doesn't handle alpha-transparency correctly by default. Therefore 
the pngbehavior.htc. It's only for IE6. And then thissolution is the 
least work. (compare other solutions on that page described)
