Hello,

In Odoo 18, I have two models:

class A(models.Model):
    _name = 'class.a'

    name = fields.Char(string='Name')
    other_field = fields.Char(string='Other Field')

class B(models.Model):
    _name = 'class.b'

    name = fields.Char(string='Name')
    a_ids = fields.Many2many(string='A_ids', comodel_name='class.a')

And I have an XML view for the 'class.b'

<record id="class_b_fom_view" model="ir.ui.view">
    <field name="name">class.b.form.view</field>
    <field name="model">class.b</field>
    <field name="type">form</field>
    <field name="arch" type="xml">
        <form>
            <field name="name"/>
            <field name="a_ids">
                <list create="False">
                    <field name="name"/>
                    <field name="other_field"/>
                </list>
                <form create="False" edit="False" delete="False">
                    <field name="name"/>
                    <field name="other_field"/>
                </form>
            </field>
        </form>
    </field>
</record>

I can add existing 'class.a' records.

I can't create, modify or delete 'class.a' records.

However, if I click on a record already selected, and if I click on the maximization button (top, at left of X close button) of the form of 'class.a', Odoo switch to the normal 'class.a' form and I can modify and suppress the record, as well as create a new 'class.a' record.

How to avoid this behavior, e.g.deleting the maximization button or hiding it?

Best regards,

Boris
