A Group can have a subgroup as a member, display the subgroup members and make the subgroup clickable.
Think about how Angular can handle recursive situation, including back button navigation. It may need refactory how to store/cache group data.
In the Directory tool, when I search for its-et-mpw, I should see members and also subgroups. The attached screen captures show MCommunity showing the subgroup and the Michigan App not showing the subgroup. The Michigan App should show exactly the same results as MCommunity.
