- class mptt.fields.TreeForeignKey(to, on_delete, related_name=None, related_query_name=None, limit_choices_to=None, parent_link=False, to_field=None, db_constraint=True, **kwargs)
Extends the foreign key, but uses mptt’s

- class mptt.fields.TreeManyToManyField(to, related_name=None, related_query_name=None, limit_choices_to=None, symmetrical=None, through=None, through_fields=None, db_constraint=True, db_table=None, swappable=True, **kwargs)
- formfield(**kwargs)
