Hi,

Please refer to the code:

<record id="view_crm_lead_kanban_inherit_tags" model="ir.ui.view">

    <field name="name">crm.lead.kanban.tags.inherit</field>

    <field name="model">crm.lead</field>

    <field name="inherit_id" ref="crm.crm_case_kanban_view_leads"/>

    <field name="arch" type="xml">

        <xpath expr="//div[@class='o_kanban_primary_bottom']" position="inside">

            <div class="o_kanban_tags mt4">

                <field name="tag_ids" widget="many2many_tags" options="{'color_field': 'color'}"/>

            </div>

        </xpath>

    </field>

</record>

Hope it helps.
