AI-generated from the code · Odoo 19.0

Adds a new "Dynamic Dropdown" field widget for Odoo forms. It lets developers show a dropdown whose options are fetched from the server, optionally depending on another field on the same form.

This module is a technical building block for Odoo developers rather than a ready-made business feature. It registers a new field widget called "Dynamic Dropdown" that can be used on char, integer and selection fields.

When a form is opened, the widget calls a method on the record's model to get the list of available options, and shows them in a dropdown. The method name is configured in the field's options, and extra context can be passed, for example the value of another field on the form. If that other field changes, the options are fetched again.

Business rules added by the widget: - If the current value is no longer among the options returned by the server, the field is automatically cleared. - For integer fields, a non-numeric or zero selection is rejected as invalid. - Empty selections are stored as no value.

To demonstrate how it works, the module ships a demo setup on the ir.filters model: a manual integer field named "Dropdown Integer" is added to the filter form, and a demo method returns a small list of options, adding one extra option when the administrator is among the selected users. This demo is only installed with demo data and is meant as an example, not as a business feature.
