Custom Radio Buttons

In some cases, you might need to create components that work like radios but don't look like radios. The React SDK exports a RadioGroup to help with this scenario. Here's what you need to do:

  1. Create a component that accepts the checked and disabled props. Be sure to forwardRef to the component because it's used for keyboard accessibility.
  2. Add the component as children of RadioGroup and pass a value prop to it.
  3. If you pass disabled to any of it's children, it'll be skipped in the keyboard navigation.
