Many2one Options Cleaner
Hide "Create..." & "Create and Edit..." Dropdown Options Globally in Odoo 19 Based on User Permissions
Stop users from accidentally cluttering your database with duplicate master data.
Control Many2one dropdown creation entries application-wide via a single security groupâzero XML view modifications required!
Why Unrestricted "Quick Create" Destroys Data Quality
By default, Odoo allows any user with write access on a form to quickly create new customers, products, or categories directly from a Many2one dropdown. This leads to duplicate records, misspelled master data, and endless cleaning work for data managers. Many2one Options Cleaner locks down these creation links globally, allowing only authorized managers to create new master records.

Key Features & Capabilities
Simple, non-intrusive, and high-performance master data protection for your Odoo deployment.
Global Dropdown Cleaning
Automatically removes "Create..." and "Create and Edit..." entries across all Many2one fields in every module without modifying any XML view files.
Role-Based Access Control
Controlled via a dedicated security group: Allow Create Options on Many2one Fields. Granted to system administrators by default, easily assignable to trusted users.
Zero Performance Overhead
The user permission check is attached directly to Odoo's session_info, cached in the web client payload with zero extra server RPC requests when opening dropdowns.
Non-Intrusive Integration
Respects existing view attributes! If a field explicitly sets options="{'no_create': True}", those restrictions remain intact for all users.
How It Works Under The Hood

- Customizable user notification toast when quick-create is restricted.
- Granular toggle between hiding "Create..." vs hiding "Create and Edit...".
