Add this to X > Theme Options > JS
jQuery(document).ready(function($){
$('.x-navbar').addClass("x-nav-trans");
$(window).scroll(function(){
if( $(this).scrollTop() > 100 ) {
$('.x-navbar-fixed-top').addClass("x-nav-trans");
}else{
$('.x-navbar-fixed-top').removeClass("x-nav-trans");
}
});
});
Add this to X > Theme Options > CSS
.x-navbar.x-nav-trans {
