Creating a menu in a new window

deb Community Member Posts: 42 ♪ Opening Act ♪
I am developing a program with 24 different chapters/modules. This makes for a long drop down menu. I set up a drop down menu, but then I can't set anything up on the pages within the program to "always be on top" or the menu falls behind those items. This is a bit of a pain as I have a lot of movement and pages that flow automatically and the drop down seems to affect some of these actions when it is open.

What I wanted to do was create a menu page that would open as a separate window so that I could custom make the menu. However, when you click on a chapter to go to, it opens in the small menu window. Is there a way to have a button from one window take you to a page in the program already open?
