menu not work as i like

You’re not providing enough information for us to even try to help

E.g:

var scrollAttrs;

scrollAttrs = {
 'data-url': false,
 'data-easing': 'easeInOutQuad',
 'data-speed': 2000,
 'data-scroll': ''
};

jQuery('#menu-item-53 > a').attr(scrollAttrs);

You’ll have to run that jQuery BEFORE the Smooth Scroll JavaScript is ran

So when you press the navigation links: “SAMPLE PAGE”, “ABOUT”, “TEST”, “TOP” and “TOP2”, you want them to return to the top of the page?

Then replace this:

jQuery('#menu-item-53 > a').attr(scrollAttrs);

With this:

jQuery('#menu-menu-xpeno a').attr(scrollAttrs);
