Hi Yuly!

In order to emulate radio buttons, an easy way would be to use "attrs" with"readonly" attributes to force select only one of the 2 options.

You can add to your model 2 boolean fields representing the 2 exclusive options then create an inherited form view as follows:

                            <field name="x_option1" attrs="{'readonly': [('x_option2','=', True)]}"/>
                            <field name="x_option2" attrs="{'readonly': [('x_option1','=', True)]}"/>

Now when you try to select an option in the form view, the other one is made readonly and vice-versa.

Hope it helps.

Regards
