Preserve view controller

[Andrei0795]

Hey! Amazing control. Very useful for many types of apps.
I was wondering about something that could help me a lot. If I select a child view controller(let's say A) for the container, and then I select another view controller(let's say B), I would like to know if it's possible to return to the same view controller A(using the menu) without creating a new view controller. Basically, every time I move from one view to another using the menu, a new controller appears and the old one is released. I found the DropdownMenuSegue class but because I'm quite new to objective C, I don't know how to preserve my view controllers. I need to keep them because my view controllers are in fact navigation controllers and I wouldn't like to lose the current view when I select a menu item and then come back.
Help would be much appreciated. Thanks!
