Can filelds.property uses many2many ?

Hello,

Yes you can set property field in many2many by adding it by following way in .py file:

        'property_account_expense_categ_test': fields.property(
            'account.account',
            type='many2many',
            relation='account.account',
            string="Expense Account (Test)",
            method=True,
            view_load=True),

Hope this will help you.
Thanks.

Is it needs to modify fields.property to make it support m2m
because , in ir.property at the field "value" it can get only 1 value

Thank you
