Hi folks:

In a standard list view, for example, it is possible to pass a context value of "{'group_by': ['<field_name']}" in the window action which results in the data in the view being displayed in a grouped form by default.

Is it possible to achieve the same result in the tree view of a one2many field in a form? Something similar to what is being described in the following blog post. The solution in the post is 7 years old and does not seem to work with Odoo 13.

Thanks much for taking the time to respond to my question.
