How to Make Your Header Navigation Sticky
Your website header is the section at the top of every page that contains your logo, navigation menu, and key links. Making it sticky keeps this section visible as visitors scroll.
To make your header navigation sticky, first go to Site Admin > Website Builder, and press the Edit Website button.

Click the header background (not the logo or navigation menu), and the Edit Header menu will appear on the right.

Under General settings toggle on Make Header Sticky.

This setting applies to all pages and ensures your header stays at the top of the screen while users are scrolling.
To make your new header go live, click UPDATE in the top-right corner to publish the change. Alternatively, click PREVIEW to see it in action before publishing.
