ラジオグループ

<%# Markup for the radio-group (APG Radio Group) demo.
    A custom card-style radio. Single selection is shown via aria-checked and the single
    tab stop via roving tabindex. Arrows move the selection (focus = selection). The group
    delegates click and keydown, so the radios carry no data-action of their own. The
    selected value is reflected into a hidden field; the look is the consumer's CSS. %>
