Sorry, I forget the explain. I want to customize only odoo studio, i do not want to use init, manifest etc..

Hi,

To create a new menu under the Products tab in Odoo 19 Enterprise, you first need a custom module (for example, product_custom_menu). Inside it, include essential files like __init__.py, __manifest__.py, and a views folder containing your menu XML file. In the manifest file, define the module’s details, add product as a dependency, and include your XML file in the data section.

Next, in the XML file (e.g., product_menu.xml), define your menu structure. Use the <menuitem> tag with parent="product.menu_products" to place your new menu under the existing Products tab. You can add a sub-menu with an action linked to a model or view, such as displaying a product list using the product.template model.

<?xml version="1.0" encoding="utf-8"?>

<odoo>

    <!-- Add a new menu under the main 'Products' menu -->

    <menuitem id="menu_product_custom_root"

              name="My Custom Menu"

              parent="product.menu_products"

              sequence="50"/>

    <!-- Example action (optional): open a list of products -->

    <record id="action_my_custom_product_list" model="ir.actions.act_window">

        <field name="name">My Custom Product List</field>

        <field name="res_model">product.template</field>

        <field name="view_mode">tree,form</field>

    </record>

    <!-- Submenu linked to the action -->

    <menuitem id="menu_product_custom_sub"

              name="Product List"

              parent="menu_product_custom_root"

              action="action_my_custom_product_list"

              sequence="1"/>

</odoo>

Finally, update your module in Odoo using the command line or the Odoo Apps interface, then install it. Once done, your new menu will appear under the Products tab, ready to open the linked model or view. Optionally, you can replace the product list with a custom model or dashboard view if desired.
