I just finished writing a new tutorial on making dropdown menus using AS3 classes. Head on over to actionscript.org and check it out: AS3 Dropdown Menu with Reusable Classes.
You will really like it. My article here on my own site that uses the timeline and frame code is good, of course, but this new approach using classes is definitely way better.

In this article, you will learn a much better, more object oriented way to structure a Flash application than the typical "frames on the main timeline" scheme that you see so often everywhere. This better way might be summed up in a few words as "MovieClips as screens." This is so far superior to "Frames as screens," that I think you will be as amazed as I was, when I line out for you exactly why. Read on!
This article on variables may be somewhat different than the kind you are accustomed to seeing. Rather than focus on what is an int, what is a Number, what is a String (and so on...), I instead choose to focus on certain aspects of variables that I consider more "off the beaten path." Also, I want to stay Flash-centric and not just about programming in general. In other words, stuff that you don't see elsewhere!
This is something that you are probably going to kick yourself over when you see how easy it is! ....
