Hidden windows / map enlargment question

Dealing with an issue that is probably not nearly as complex as I think.

I have a general-overview map (image 1) with 8 large GUI buttons labeled as quadrants. What I want is for clicking on each ne to bring up a zoomed-in view of that section of the map, while removing the quadrant buttons so they don’t overlay the zoomed map (see image 2). THe problem is I can’t figure out how to do that. I’ve been assuming that it has something to do with enabling/disabling renderers and sending messages between seperate objects. Any help is appreciated.

What it should look like after clicking the “quadrant” button:

Ok well I’ll keep working on it
