Hide widget within another widget display constraint

How do i hide a widget within another widget display constraint?

Take for example:

I have a throbber and a circular minimap. Throbber is tied to a moving object and it moved out of the circular minimap (which is an image in umg). So how do i hide the throbber within the minimap without it showing on to the screen?

i have managed to solve it using a retainer widget, using it to contain all the other widgets via a layout widget.




I might have screwed up using the material as i am no expert with it. But this works for me.
