OR

any other way how i can inherit and add editable treeview to allow user to create multiple records or rows.

OR

its not possible ... because of Odoo restrictions.

don't know why, here in Odoo forum, it seems most of the times people Answer and gone... like it has been resolved but it was not and nobody else is trying to help, so i create another topic.

anyway please help.
