Learn how to use the Selection Widget in Odoo for dropdown fields with predefined options, ensuring data accuracy and user-friendly interfaces.
The Selection Widget in Odoo is a helpful tool that allows developers to create fields where users can choose from predefined options. This widget, defined using widget="selection", is commonly used in form views to enhance data accuracy and user experience by restricting input to a specific list of values. It ensures data consistency while giving users an easy way to select from available options.
To use the Selection Widget, first define a selection field in your model. Here's an example:
from odoo import models, fields
class ProductTemplate(models.Model):
_inherit = 'product.template'
product_type = fields.Selection([
('consumable', 'Consumable'),
('service', 'Service'),
('stockable', 'Stockable Product')
], string="Product Type")
In this example, a field named product_type is created with three predefined options: Consumable, Service, and Stockable Product.

<form string="Product">
<group>
<field name="product_type" widget="selection"/>
</group>
</form>
