Menus

Does anyone know how I can make (or get the code to, OR find a generator) to make CSS Multi-Level menus Such as the Habbox menu. Example:

NEWS-When clicked becomes
example
example
example
FORUM-When clicked becomes
example
example
example
example
HELP-When clicked becomes
example
example

Do you get what I mean?
Rep to the person(s) who can help!

I dont really like the style of that, and it isn't customizable enough. Anyone else with code or a generator to make one? Just like Habbox's but plain text.
