Hi, I have the problem that I scroll buttons inside a panel but when they are outside the panel you can always see them... ugly!
How can that be changed? I don't find anything about that in the manual

Edit: The same question but explained better, i hope

In my interface I have a panel and in this panel are a few buttons and a slider. the slider changes the y-positions of all the buttons inside the panel. I want that you can't see the buttons when they are out of the panel.
