So I was wondering, what do you use to create one page template’s menu, that sticks on the top when you scroll and menu items changes according to page sections. Do you prefer to use any plugin or any tips and tricks you want to share
Thanks for the help in advance 
Sticking the nav on top is as simple as adding a CSS class on scroll event via jQuery, or just make it fixed via CSS no matter of the scroll position. As for the active links on scroll, you can check out this - http://imakewebthings.com/waypoints/ it’s really neat.
Good luck with your theme design
