There is a "My Groups" link...
Thanks Janettee, but my intention is to show in the list of all groups which the user has already joined to.
Unless I'm misunderstanding - that's exactly what I just told you.
Hi Janettee, the link you suggested is the one on the top of that page to enter in another list of only the user's groups. But I need to show in the list of all groups the ones the user already joined to, adding any mark or text beside it without redirecting to another page.
My network is about beer brands from the world and each group is a specific beer brand with its details, when a user joins a group is actually creating a collection of beer brans already tasted. There are about 600 groups (beer brands) and will reach about 2000. Each user will have about 40 groups (beer brands) and many users already complained that while seeking for a group (beer brand) in the list, there's no visualization of the ones already joined to and I noticed that some users doesn't come back to finish its "beer collection" due to that.
