Allow listing direct members only in group members page
Problem to solve
Mentioning a subgroup only mentions direct members: https://docs.gitlab.com/ee/user/group/subgroups/#mentioning-subgroups
For instance, mentioning
@gitlab-org/maintainers/rails-backend does not mention all members of
@gitlab-org, only the people who are explicitly added to that subgroup. This is a very useful feature! But, it's hard to know who's going to be mentioned when you type
@gitlab-org/maintainers/rails-backend, because the members list shows all users, including those with inherited access: https://gitlab.com/groups/gitlab-org/maintainers/rails-backend/-/group_members
Anyone who administers or @-mentions groups.
We should add a filter on the group members page to see who's a direct member.
Permissions and Security
This should use the same permissions as visiting the group page.
This should be a UI change to expose the internal database structure more clearly.
What does success look like, and how can we measure that?
I don't know how to answer this question. I think implementing this feature would be success in itself; we'd reduce the confusion over where people get their access. We could measure it anecdotally by tracking questions in the GitLab Slack (I think this has come up three times this year that I've seen, and I don't read everything in our Slack)?
