var header_top = jQuery('#header-top-wrapper');
var header_top_button = jQuery('#header-wrapper a.accordion').addClass('active');
var header_top_height = header_top.height();
header_top_button.click(function() {
if(header_top_button.hasClass('active')) {
header_top_button.removeClass('active');
header_top.css({'overflow': 'hidden'});
header_top.stop(true, false).animate({"height": "0px"}, 500, function(){
});
}
else {
header_top.stop(true, false).animate({"height": header_top_height + "px"}, 500, function(){
header_top_button.addClass('active');
header_top.css({'overflow': 'visible'});
});
}
});
