Building A Flash Drop Down Menu?

HOW do I go about doing it?Ive tried...buttonon "over" create to movie clipinside movie clip have my animations and sublink buttonsit works fine, but there's one problem, The hit area of the main button HAS to cover the hidden sublinks, so even if you scrolled your mouse over the bottom of the button (in the invisible area) it will still show since its in the hit area).How can I create a simple nav drop down? I seriously have went through almost all tutorials, both video and text, and nothing has worked! I am using Actionscript 3, or whatever the tutorial says to use.edit: Here is something I'm working on. Its a button, and on the rollover it creates the animation. Obviously it doesnt work, because you cant have a button inside a button, so I don't know the actionscript to do this.
