I've tried and it's not possible.
After thinking a while I understood why. Let me explain my theory:
A belongs to categ1 categ2
B belongs to categ 2 categ 3
C belongs to categ1 categ 3
Okay if you list this three items:
But if you try to group them by categ. You'll have to repeat A two times B two times and C two times. Group doesn't intend to repeat data it just group the data into sets without common data.
If group worked on many2many it'll do something like this.
- categ1: A C
- categ2: B
- categ2: (empty)
Because it'll show only once the registry and it'll catch them by priority.
Anyways this doesn't work. So if you want to group a many2many you have to do it by python code it's a little bit complicated but I think that there is a way to do it.
