Copying child widget in the parent container.

I am trying to copy on of the widgets of the parent container and adding it in the parent container itself but can't find the correct way to do it. 

What i am doing is that : 

First i copied the child container which i want to add, but whenever i try to add it by clicking on the layout of the parent it directly says that "cannot be directly copied to parent", so even if i try to add a new widget otherwise, it drags to some other children element and not to the parent element.

.

As you can see in the picture below, when the widget is dragged it highlights the other children widget and not the parent.

This is the heirarchy below and I want to copy and add this "container 40" into the parent "container 25". So as to get an identical widget.

Update: I figured how to copy it but the widget looks out of place in the runtime as compared to the mashup
