Is it possible to disable buttons on lower level

Not sure if anyone has answered this yet as i’m a junior member,
I was wondering if they is a way to disable a button on say level 3 once you place another movie over top over it on say level 5. The problem I’m having is that i have a virtual store plan
that has buttons all over with sound and when i load a sub menu beside it or on to it you can hear the sounds from the button below. I can’t move the sub menu to a blank spot because it will be to far away from the button that loads it. By the way the buttons that i would like to disable are on the root, so maybe the root could be set to hide or invisible or something when it loads a sub menu . Sorry if this is long. Could really use some help.
