This is the community forum of the forum software named NodeBB. It is not a forum for general Node.js questions. Though they are, of course, allowed, you'll have better luck on StackOverflow or elsewhere.
There are not hierarchical permissions in NodeBB. If you would like to see hierarchical permissions, you could open an issue on our Github page and request such a feature.
I do believe we have a way of copying permissions between groups, so that could help you out in doing what you want.
