Radio group

Radio Group

Allows single selection from multiple options.

Anatomy

To set up the radio group correctly, you'll need to understand its anatomy and how we name its parts.

Each part includes a data-part attribute to help identify them in the DOM.

Design impact on the asChild property

The RadioGroup.Item element of the radio group is a label element. This is because the radio group is a form control and should be associated with a label to provide context and meaning to the user. Otherwise, the HTML and accessibility structure will be invalid.

If you need to use the asChild property, make sure that the label element is the direct child of the RadioGroup.Item component.

Examples

Learn how to use the RadioGroup component in your project. Let's take a look at the most basic example:

Disabling the radio group

To make a radio group disabled, set the disabled prop to true.

Setting the initial value

To set the radio group's initial value, set the defaultValue prop to the value of the radio item to be selected by default.

Listening for changes

When the radio group value changes, the onValueChange callback is invoked.

Using the Root Provider

The RootProvider component provides a context for the radio-group. It accepts the value of the useRadio-group hook. You can leverage it to access the component state and methods from outside the radio-group.

If you're using the RootProvider component, you don't need to use the Root component.

API Reference
