group_mapping_from_node
This module adds a configuration section to a node form to select a Group and make it part of it.
By Default, Group module does not allow to map a node to a group from the node itself, however, there is a specific way it needs to be done.
Group administration page has one section called Related Entities, where an existing or a new entity can be attached to a group.
Right now module gives flexibility to the content author to make a node part of a Group without following multiple steps with different places and administration screens but form single place.
*** Please make sure you enable the Group Content Plugin for the content type where Group Tagging is needed on the node edit form, otherwise, the configuration section will not be displayed. ***
