Hierarchical tree-style dropdown for Many2one fields

Browse and select Many2one records through an expandable, indented tree dropdown instead of a flat list

The standard Odoo Many2one dropdown shows all matching records in a simple flat list, which loses the parent–child structure of hierarchical models (e.g. product categories, locations, departments). This module replaces the dropdown with an interactive tree where users can expand or collapse parent nodes, see child records indented beneath their parents, and pick the exact record they need with full context of the hierarchy — all in real time as they type. The tree is built and cached on first search and the dropdown is always positioned below the input with its width matched to the field, ensuring a consistent and polished look.
