@enricostn @xavier.bonet We can assure that base.main_company will be always the instance company? This is the logic added in the post init hook.

Features

New hierarchy_level selector field in res.company
Constrains on hierarchy_level
- Can only be one instance company
- instance company can't have any parent_id company
- coordinator parent hierarchy_level must be instance
- community parent hierarchy_level must be coordinator
Added parent_id_filtered_ids computed field to create dynamic domain to parent_id depending on the hierarchy_level
Added parent_id field to easy_company_creation (Domain is not dynamic, we only create community type here)
Added unit test. (Feedback is appreciated 😅)
Post init hook assigns instance to base.company and the children company coordinator
