$page->addHookAfter('render', function ($event) {

    if ($this->page->template != 'admin') return;

    $js = <<< HTML
 <script>
 $(document).ready(function(){
    $("input:radio:checked").data("chk",true);
    $("input:radio").click(function(){
        $("input[name='"+$(this).attr("name")+"']:radio").not(this).removeData("chk");
        $(this).data("chk",!$(this).data("chk"));
        $(this).prop("checked",$(this).data("chk"));
    });
});
</script>
HTML;

Like this?

[tpr]

Liked that

Should be part of core. Disabled by default, enabled optionally Same goes for InputfieldSelects
After all, how can we make them really required if one is always selected, even by default?

I like the way tpr and netcarver rule their game....

Unfortunately does not work with ver. 3.x, is an upgrade planned? Another solution?
