I have a many2many field which will open a window to select language. and i one the field view of many2many to be the same as one2many field that have add an item link.
I have try to use widget="one2many" in the xml file on my many2many field, the result of the view is same as what i want but when i click "add an item" it's not showing the list of language anymore but it's show the form to create language instead. is it possible to change the Add button to "Add an item" same as one2many field?
