I want a single page scroll with top nav menu scroll and active (Active menu should be in first position scroll)

Question

I am not able to scroll Nav menu with left or right position. This should be work automatically when page is scrolling.

For Examples :

1. if "Menu 2" active then scroll position on first for Menu 2
2. if "Menu 3" active then scroll position on first for Manu 3

That above scroll and position should be automatically active on page scroll.

It is working for me when i am clicking on to the each menu. Because page scroll with top position is working fine. On click it is working but on scroll it is not working for me.
