Hello,

I am searching for adding a custom module fields for portal in odoo 12 but didn't find anything working. I have to add some custom module fields to portal(website) but unable to do that even i am not able to add a header menu in the portal. here is my code:-

portal.xml

<?xml version="1.0" encoding="utf-8"?>
<odoo>
    <data>
<template id="case_menu" name="Case Management" inherit_id="portal.portal_my_home" priority="22">
    <xpath expr="." position="inside">
        <li class="list-group-item">
            <span class="nav-item" t-esc="case_title"/>
            <a href="/mycase"> Case Management Form</a>
        </li>
    </xpath>
</template>
    </data>

</odoo>

Can anyone help me on this please? let me know if more detail is required.
