fieldgroup.module in Content Construction Kit (CCK) 6.2
Same filename and directory in other branches
Create field groups for CCK fields.
Hooks for other modules to intervene include:
- hook_fieldgroup_view: Alter the group $element added to $node->content.
- hook_fieldgroup_form: Alter the group portion of the node form.
- hook_fieldgroup_types: Add additional fieldgroup group_types.
- hook_fieldgroup_default_settings: Add additional fieldgroup default settings.
- hook_fieldgroup_save: Do additional processing when a fieldgroup is saved.
