            %p Looks like you don't have any groups yet.
            %p
              You can create groups and add users to them using the
              %i.fa.fa-fw.fa-users
              icon in the navigation on user profiles that are not yours.
            %p.mb-0
              Once you have done that, the groups will be listed here and
              when selected, you'll get a timeline view of all users from
              that group.
        - current_user.groups.each do |group|
          %a.dropdown-item{ href: group_timeline_path(group.name) }= group.display_name
