I have this example of a diagram and I would like to show that "Строка1.1" and "Строка1.2" are subordinates of "Строка1".
I think it would be great to show this by indenting packages of "Строка1.1" and "Строка1.2" a little to the right, but I have no idea how to do that.
Or maybe I can show that by giving the packages a dotted border, but it doesn't seem to be possible. Is there any way to create "subordinate" packages?
