radio constant

String const radio

A checkable input in a group of radio roles, only one of which can be checked at a time.

Authors SHOULD ensure that elements with role radio are explicitly grouped in order to indicate which ones affect the same value. This is achieved by enclosing the radio elements in an element with role radiogroup. If it is not possible to make the radio buttons DOM children of the radiogroup, authors SHOULD use the aria-owns attribute on the radiogroup element to indicate the relationship to its children.
