This plugin allows groups to be created as sub-groups of groups. 



  • Subgroups behave exactly as regular groups
  • Subgroups can be open or closed membership
  • Subgroups initially inherit any styles from the parent group (using group_custom_layout)
  • Subgroups can themselves have subgroups
  • Option to display/hide subgroups in default group listings all/mine/owned as well as those provided by group_tools closed/open/alpha
  • Option to list groups alphabetically in personal group listings
  • Sub-groups listing on default groups profile page
  • Sub-groups widget for use with widget_manager on groups profile page


Properties of Subgroups


- only members of the parent group can join a sub-group

- sub-groups are fully qualified groups in their own right, may have sub-groups of their own

- infinite depth of sub-groups

- breadcrumb navigation on group pages shows path from parent to current group

- groups owner block contains link to parent group- groups owner block contains link to subgroups

- when users leave a parent group, they are removed from all subgroups




Creating a subgroup

- subgroup automatically inherits colors/backgrounds from parent if group custom layout is used


Deletion of a group

- if the group has subgroups, all subgroups will be deleted

- content within subgroups can be reassigned to the original owner, to the parent group, or deleted


Updating a group

- if the group has subgroups, and the visibility of the group becomes more restrictive, the visibility of subgroups is updated to be at least that restrictive
