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!

Odoo 19 OWL Compatible

Permission-Driven

Zero View Overrides

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.
