I took a quick look and it should still work — but it does depend on your group’s permissions. Someone needs to be able to view the group’s page to be able to see the group listed on the about page.
Trust Level 4 for example, defaults to only being visible to logged-in users. So you’d have to go to the group, then manage > interaction and change “who can see this group?” to Everyone for logged-out visitors to see it.
This is a limitation of how this component works, because it fetches the group page data. We’re planning on adding this functionality into Discourse by default, and at that point we might be able populate users here without also exposing the group page. Not sure how those details will work out yet.
I actually have a use case where this is the desired behaviour.
Currently there is a group who have the moderator status in the back end, but they aren’t actually doing moderation. So I don’t want them listed in the moderator section on the about page.
However I do want to list them as a group on the about page using this theme component.
So if you were ever going to change the behaviour, I would suggest a test to see if the group being added to the about page is included in the hidden list. If the group to be added is also hidden, then the hiding should be ignored.
However if it wasn’t, then as far as individuals are concerned, if they are in a hidden group then should be hidden in the display list of any other group.
Not sure if that makes sense or if that would be the best implementation.
