+# dlv_partner_child_address_street
+
+## Overview
+
+In the partner form, the **Contacts & Addresses** tab lists child records as
+kanban cards. For address-type children (delivery, invoice, other, ...) the
+standard card shows only zip, city and country, so several addresses of the
+same company look identical.
+
+This addon changes those cards in two ways:
+
+1. **Street and street2** are added to address-type children. Each is shown on
+   its own line and omitted when empty.
+2. **Email is moved** from directly under the name to below phone/mobile, so the
+   name, address and phone read as one block. This applies to all child cards,
+   including contact (person) children.
+
+Resulting order: name, function, street, street2, zip/city, country, phone,
+mobile, email.
+
+## How it works
+
+Pure view inheritance of `base.view_partner_form`; no models, no Python, no
+extra fields. `street` and `street2` are already loaded by the standard
+`child_ids` kanban, so no additional data is fetched. An xpath inserts the line
+before the zip/city block, inside the existing `type != 'contact'` condition. A
+second xpath moves the existing email `div` after the mobile `div`
+(`position="move"`).
+
+Street and street2 are not shown for child contacts (persons); only the email
+move affects them.
+
+## Scope
+
+- Only the inline `child_ids` kanban of the partner form.
+- Other views (sale order address popup, partner kanban, ...) are not touched.
+
+## Compatibility
+
+- Odoo 16.0 (Community and Enterprise)
+- Depends on: `base`
