I'm considering having multiple groups, for example there could be three tabs called "cities", "people", "organizations" each of them internally are nothing but groups with same functionality.
Only difference being, if someone clicks on "People" tab user sees only those groups which are opened under "People" tab.
If someone clicks on "Organization" tab user sees only those groups which are opened under "Organization" tab.
I hope the question is clear. Appreciate if someone can confirm a way to do it.
