Organic groups subgroups

Description

The Organic Groups Subgroups module (also referred to as the 'og-subgroups'
module) enables a user with the proper permissions to build group hierarchies
(or tree) by nesting groups under other groups. Simple or complex group
hierarchies can be easily created using subgroups.

Subgroups can automatically inherit the users and/or permissions of the parent
group, but can also have additional specific users and permissions. Members can
collaborate effectively within their respective groups and subgroups, sharing
relevant content and resources.

When a hierarchy has been established, user memberships and/or content posted to
a group can be propagated up, down or sideways along the tree. So when a user
joins a group, their membership can also get created in other parent, child or
sibling groups. Separate propagation settings can be applied for content and
membership propagation.

There are two types of propagation:

1. The first type is Group user inheritance that allows users of a group to
   propagate to subgroups.

2. The second type is Group user permission inheritance that determines how
   permissions are applied to inherited users including group administration and
   access to group content.

This allows an entity's membership to be propagated up or down the group
hierarchy when adding a new group or group content to an existing group.

Installation & Configuration

Install this module using the official Backdrop CMS instructions

For basic user membership inheritance:

1. Go to the OG field settings page (admin/config/group/fields).
2. Select a bundle to attach the inheritance field to using the Entities dropdown.
3. Select the Group user inheritance field in the Fields dropdown.
4. Click 'Add field'.
5. Navigate to the content type to configure field defaults if desired.

This module provides two fields under /admin/config/group/fields:

• Group user permission inheritance: Determines how permissions are given for inherited users
