Obviously you cannot put a Container into a Container.
You can, however, put a Container into a Div, and then you can put that Div into a Container.
Once the Div with the Container is inside a higher level Container, you cannot add another Container to the Div, nor can you copy/paste a Container inside the Div, however you can duplicate the existing Container as many times as you want, which (unless I’m mistaken) allows you to break the rule of not being allowed to place a Container inside a Container.
I’m not sure if this makes sense, so just watch the attached animated .gif (right click on the .gif and open in a new tab to see it at full size.)
