How to make sub meny?

Hi!
Have a small problem. I just started playin in flash and doin my first site, so this page really helped me out! Uhm, my problem is quite hard to explain for me cus im swedish n all… =)

But here it is hope u understand! I want to make a submeny under the main meny. For example: | INFO | STUFF | OTHER |

(and when i klick on INFO other options shows)
INFO > ME, THE SITE, WORK

then here is the problem, how do i do this so when i have klicked on INFO that the sub meny stays even if i change scene. I use the time line WAY to much, very bad to put in movieclips and stuff like that. So plz help me…

Thanks!
