I have one question that i do not know how to resolve.
I attached you my context.
One parent and invisible rectangle with 2 children rectangles at both sides.
The thing is that when i click on the parent (the invisible white part where the text is) i can move the whole of it. However, if i click and move at one of the other colored rectangles, just this rectangle is moved.
What i want is to make those 2 rectangles static (to cannot move them) and if you try to move them, is the parent the one who moves (like if you were clicking at it).
