Javascript or Css Menus
The first choice is whether to use javascript at all. There a decent css option provided by CSS3Menu. Not sure why that program is so dam huge for something that could be done at a javascript program.
MooTools Options
There are plenty of javascript options out there, most of course in jscript. My (current) javascript library of choice is MooTools... (maybe I should look for a mochikit option)
Of course you should keep in mind that you should look for at least one decent list of options.
Mostly they all look the same and recommendations seem to boil down to personal preferences. Just too many to look at so I quickly setteled on two.
MenuMatic and UvmiTools Dropdown Menu.
MenuMatic
MenuMatic has the advantage of using javascript but using fallback to pure css as with css3menu above. Nice but not sure how much it matters in a practical sense.
UvmTools
UvmiTools Dropdown Menu. is the only one I found in the list above that correctly handels the delay issue. Namely that you can drag from level 2 to level 3 diagonally over a level 2 item below without loosing the level three list. A UI refinement to be sure but a pet peeve of mine so I'll try this one first.
