Hi,
In a custom class defined using the v8 API, the options 'create' and 'create_edit' in the .xml doesn't seem to hide the corresponding drop-down menu entries.
Field definition:
emergency_contact_id = fields.Many2one('hr.employee.family.member', string='Emergency contact', domain="[('employee_id', '=', id)]" )
View:
<field name="emergency_contact_id" options="{'create_edit': false, 'create': false}"/>
