Hello guys,
In the product form view, we have this :
<group name="procurement_uom" position="after">
<group string="Procurement method" attrs="{'invisible': [('type', '=', 'service')]}" groups="base.group_user">
<field name="route_ids" widget="many2many_checkboxes" />
</group>
<group string="Supply method" attrs="{'invisible': [('type', '=', 'service')]}" groups="base.group_user">
<field name="route_ids" widget="many2many_checkboxes" />
</group>
</group>
This code displays this :

How to display each route in the good column instead of all the routes in both columns.???
UPDATE #1
