Why is my overflow dropdown menu on top of the actionbar?

Question

By default isn\'t it supposed to be under the actionbar? So what am I doi

Answer 1

This is the new default with Material Design. Popup menus will be displayed originating from the Button which opened them.

This is done to increase the visual connection between the Button and the popup menu. Just look at Googles apps which already use Material Design, there the popup menus act in the same way.
