Learn how to use the Selection Widget in Odoo for dropdown fields with predefined options, ensuring data accuracy and user-friendly interfaces.

How to Use the Selection Widget in Odoo

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.

How to Define a Selection Field in Odoo

To use the Selection Widget, first define a selection field in your model. Here's an example:

xml

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.

Adding the Selection Widget in Form View

Once the selection field is defined, you can use the widget="selection" attribute in your form views to display a dropdown selection. Here's how to implement it in XML:

xml

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

By adding widget="selection", the system renders a dropdown in the form view for selecting from the predefined product types.

Advantages of Using the Selection Widget

Using the Selection Widget provides several benefits:

  • Data Integrity: The widget ensures that users can only select from predefined options, thus maintaining consistency.
  • User-friendly Interface: The dropdown menu simplifies the user experience by offering a clean and easy-to-navigate interface.
  • Efficiency: By restricting inputs to a set of values, you reduce errors and improve the speed of data entry.

When to Use the Selection Widget in Odoo

The Selection Widget is ideal for use in scenarios where you need to control the input values in a field. Some common examples include:

  • ▹ Selecting product types (e.g., consumable, service, stockable)
  • ▹ Status fields (e.g., draft, confirmed, done)
  • ▹ Priority settings (e.g., low, medium, high)

Conclusion

The Selection Widget in Odoo is a valuable tool for limiting field values to a set of predefined choices. By using widget="selection", you ensure data consistency while improving the usability of forms. This widget is perfect for fields that require users to choose from a controlled list, such as product types, statuses, or priorities, providing an efficient and user-friendly solution for data input in Odoo.
