Replace fields.Selection with a Many2one field pointing to a new model.

Here’s how:

🔧 Step 1: Create a new model to store the options

python
CopyEdit
from odoo import models, fields

class CustomOption(models.Model):
    _name = 'your.model.option'
    _description = 'Selectable Options'

    name = fields.Char(string="Option", required=True)

✏️ Step 2: Replace your Selection field with a Many2one field

In your main model:

python
CopyEdit
from odoo import models, fields

class YourModel(models.Model):
    _name = 'your.model'

    option_id = fields.Many2one('your.model.option', string="Option")

🧑‍💻 Step 3: Enable adding new options from the dropdown

In the form view XML:

xml
CopyEdit
<field name="option_id" options="{'no_create': False}" context="{'default_name': 'New Option'}"/>

This allows the user to:

  • Select an existing option
  • Create a new one directly from the dropdown

✅ Done!

Now users can add and choose options freely, just like a dynamic selection list.

Let me know if you want to restrict who can add options with access rights!

Hello Jihane

Users cant add a value to the selection field as its modified only using python code
However you can implement the same thing by Creating a new model and instead of using a selection field you can use a Many2one field and then give users access to this new model so they can add values

Hope this helps

Hi,

Step 1: Create a New Model for Selection Options


Create .py file


from odoo import models, fields


class CustomSelectionOption(models.Model):

    _name = 'custom.selection.option'

    _description = 'Editable Selection Options'

    _order = 'name asc'  # Sort alphabetically


    name = fields.Char('Option Value', required=True)

    active = fields.Boolean('Active', default=True)


Step 2: Add Many2one Field to Your Main Model


Create .py file


class YourModel(models.Model):

    _inherit = 'your.model'  # e.g., sale.order, product.template


    custom_selection = fields.Many2one(

        'custom.selection.option',

        string='Custom Selection',

        help="Select or create new options"

    )


Step 3: Set Up Security Permissions


Create security/ir.model.access.csv:


id,name,model_id:id,group_id:id,perm_read,perm_write,perm_create,perm_unlink

access_custom_selection,custom.selection.access,model_custom_selection_option,base.group_user,1,1,1,0


Hope it helps
