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 references the view being extended. xpath locates where to inject or modify content.

You can use position="after", before, replace, attributes,etc.

mode="primary" 

Declares this view as the main view for the model. Only one view per type (e.g., form) can be primary. Used instead of overriding existing view IDs.

    product.category.view.form.your.module2

    product.category

    primary
