PHP Code:

$(document).ready(function() {
           // put all your jQuery goodness in here.
           // Do not instantiate elements until the document has finished loading
         
            //jQuery Easy Accordion 
            $('.accordion-list:not(:first)').hide();
         
            $('.accordion-list:first').hide();
         
            $('.accordion-header:first').addClass('active');    
            $('.accordion-list:first').addClass('content-active');
         
            $('.accordion-header').click(function () {
                $('.accordion-list:visible').slideUp().prev().removeClass('active');
                $('.accordion-list:visible').removeClass('content-active');
