How to define the boundary of a moving in frame

On the topmost of my app wireframe is a menu bar.
By clicking and dragging an image downward just below the menu bar.
A overlay frame would moving in from top follow the drag position.
The problem that I encounter is the overlay frame has cover the menu bar while moving in, how to make the menu bar always on top and ensure the overlay frame start point after the menu bar?
