looks like its just a movieclip with different animations triggerd by rollover or roll out

if you have a movieclip make a stop on teh first frame, as well on this frame make a trigger button (a button with only a hit state) and on rollover have it play the clip, from frame 2 to whenever the animation of your menu stuff coming out. during thistime you have a different trigger that watches for a roll out if the user is to roll out then you jump to the animation of the menu closing.

try it out good luck
