The Radio Control should never be used in isolation, but as part of other components.
Overview
A Radio Control is an interactive area where users can make single selections. It’s bare-bones and doesn’t include a Label or Helper text.

How to use
This control should always be used as part of other components, contextualizing the action user is performing by using it.
Please, note that this control not is meant for isolated usage but as part of another component. For Radio groups, we plan to incorporate Selection groups soon. In the meantime, we’re here to support you.
Behavior
States
The state of a component can depend on properties set before people can interact with it. We call them state properties. Differentiating them from the user-triggered states allows us to combine them, creating richer states that cover the whole interaction spectrum.

Error variants
ReadOnly variant
When the property ReadOnly is true, people can’t edit the control. ReadOnly displays values in an accessible way so that users can read them. ReadOnly control can be focused and hovered but can’t be interacted with.
Disabled variant
When the property Disabled is true, users can't edit the control. A Disabled control cannot be focused or hovered.
