First let me start by saying this is my first ever map, so if this is a noob question, I apologize. 
Basically what I'm trying to do is create more ability slots. For example, if the player click the ability "Shape Shifts" it will open a new menu type area with more ability slots (ability slots being the slots where you have things such as move, stop, attack move, hero abilities, etc.). I will also need to know how to create a button to return to the original ability area. How can I do this? I have played maps where it has been done...
Again, this is my first map, so please explain things in a noob friendly way.
