Basically I added a new field on crm.lost.reason model called type. Now what I'm trying to do is to list down the list reason based on the type.

Model: crm.lead.lost

XML Form

<?xml version="1.0"?>

<form string="Lost Reason">

<group class="oe_title">

<field name="lost_reason_id" domain="<add condition to only list lost_reason_id.parent.type = 'xx type'>" widget="selection" />

</group>

<footer>

<button name="action_lost_reason_apply" string="Submit" type="object" class="btn-primary"/><button string="Cancel" class="btn-secondary" special="cancel"/>

</footer>

</form>

I want add a domain to filter only the reference table type = 'xxx value'. Is this possible? I'm trying it on Odoo studio 12 trial version.

Thanks
