Hi ,
<blockquote>
How can I remove the jerkiness of the top panel when scrolling?
</blockquote>
Please open file “templates/ja_muzic/js/script.js”, find and remove code
(function(){
// Add class for mainmenu when scroller
var min = null,
sid = null,
mainnav = $('#t3-mainnav');
if(mainnav.length){
$(window).scroll(function() {
if(min != $(window).scrollTop() > mainnav.outerHeight(true) *0.4){
min = !min;
min ? mainnav.addClass('affix') : mainnav.removeClass('min-mainnav');
//force reflow
mainnav[0].offsetWidth;
min ? mainnav.addClass('min-mainnav') : mainnav.removeClass('affix');
}
})
}
})();
Regards
