         <div id="selectalign">

<aui:script>
AUI().ready('node', 'event', function(A){
    A.all("input[name=<portlet:namespace/>nationalholidays]").on('change', function() {
        var nationalholidaysType = A.one("input[name=<portlet:namespace/>nationalholidays]:checked").get("value");
        if(nationalholidaysType == "yes"){

        }else{
            A.all('.running').hide();
        }
        });
   
    });
