Help with sofisticated dropdown menu

I tried to make one of those dropdown menus where you have the rest of the menu move down if you open a dropdown. Kinda hard to explain with words :/. I cant find an example either.

I quickly found out that I wouldn’t be able to do this with AS tweens though hehe. Heres what I came up with: http://hundsteg.se/Erik/menutesting.swf

if you press “meny2” you will see what I’m trying to achieve. If you press “meny1” the “meny3” will stay still though. Can’t work that out with just tweens.

Anyone know how to do this? Or have a tutorial or something?

Thanks!
