Members Online Widget is a XenForo 2 add-on for XenForo 2.2+ (fully suitable for 2.3.x) that adds a flexible public widget for showing who is active in your community. It supports multiple display modes, activity source switching (currently online or active in the last 24 hours), and usergroup-based filtering for cleaner, role-focused visibility.
The addon also includes an optional clickable usergroup footer that links to a dedicated group page, where members can view users from that selected group in a simple paginated list.
