How it works

Scrollspy has a few requirements to function properly:

Scrollspy for more bootstrao components Bootstrap Scrollspy documentation

It must be used on a Bootstrap nav component or list group.
Scrollspy requires position: relative; on the element you’re spying on, usually the <body>.
Anchors (<a>) are required and must point to an element with that id.

When successfully implemented, your nav or list group will update accordingly, moving the .active class from one item to the next based on their associated targets.

Scrollable containers and keyboard access

If you’re making a scrollable container (other than the <body>), be sure to have a height set and overflow-y: scroll; applied to it—alongside a tabindex="0" to ensure keyboard access.

Scroll the area below the navbar and watch the active class change. The dropdown items will be highlighted as well.
