Here's how you can use view inheritance in Odoo to extend or modify existing views. I'll cover both the 'extension' and 'primary' modes. View Inheritance: mode="extension" This is the default mode and allows you to extend an existing view without overriding it. You can have multiple extension views for a single primary view. product.category.view.form.inherit.your.module2 product.category extension 'inherit_id' specifies the view being extended, and the `xpath` expression determines where to add (`position="after"` in this example; other options include "before", "replace", "attributes"). View Inheritance: mode="primary" This mode lets you create a completely new primary view while still referencing an existing view's structure. Only one view can be primary per model and view type (e.g., form). product.category.view.form.your.module2 product.category primary
