Learn how to use the Many2many Checkboxes and Many2many Tags widgets in Odoo to create a flexible and user-friendly interface for selecting multiple records.
In Odoo, the Many2many field allows you to create a relationship between multiple records in two different models. To enhance the user interface and improve usability, Odoo offers two primary widgets for managing Many2many fields: the Many2many Checkboxes widget and the Many2many Tags widget.
The Many2many Checkboxes widget in Odoo allows users to select multiple options by displaying checkboxes next to each record. This widget is especially useful when you want users to select items from a list and need the interface to be clear and direct.
You can easily implement the Many2many Checkboxes widget by specifying the widget="many2many_checkboxes" attribute in your form view. Here’s an example of how to use it:
<field name="category_ids" widget="many2many_checkboxes"/>
In this example, we are displaying the category_ids field with checkboxes, allowing users to select multiple categories from the available options.
The Many2many Tags widget is another useful widget for Many2many fields. It displays the selected records as tags, allowing users to remove or add more items dynamically. This widget provides a visually compact and user-friendly interface, especially when managing multiple relationships.
To implement the Many2many Tags widget, you can specify the widget="many2many_tags" attribute in your form view. Below is an example of how it can be applied:
<field name="category_ids" widget="many2many_tags"/>
With this configuration, the selected categories will be displayed as tags, and the user can easily remove or add tags by clicking on them.
While both widgets work with Many2many fields, they offer different user experiences:
Both widgets are useful in different scenarios:
Let's consider a scenario where you have a field called category_ids in a product form. You want the user to either select categories using checkboxes or see them displayed as tags. Here's how you can set up both:
<form>
<group>
<!-- Many2many Checkboxes -->
<field name="category_ids" widget="many2many_checkboxes"/>
<!-- Many2many Tags -->
<field name="category_ids" widget="many2many_tags"/>
</group>
</form>
The Many2many Checkboxes and Many2many Tags widgets in Odoo provide flexible ways to display Many2many fields. Depending on the user interface requirements, you can choose either checkboxes for a straightforward selection interface or tags for a more compact and dynamic user experience. Understanding when and how to apply these widgets can enhance the usability of your Odoo applications.
