Radio buttons need to be grouped for proper interaction

[chris-morgan]

Radio buttons should always belong to a group, so that things like the arrow keys work to select a different value, and so that accessibility tools can understand what’s going on with them.

In HTML, this means that grouped radio buttons need to share a name attribute.

Yes, I agree.

This should also improve their API and ensure you cannot use them as a multiselection widget, where checkboxes would make more sense.

The main challenge here, in the long run, will be styling flexibility.
