Turning a menu on and off onclick in hololens

I have a project that i'm working on, where there is an interactive solar system in the hololens. I've gotten to the point where I have all the planets rotating with hit boxes around each of them. I also have it so that when I click on each planet, it instantiates a menu, but the menu is stuck to the planet and I can't figure how to activate and deactivate it.
