Looking for Table of Contents Plugin with Scrolling Active States

Does anyone know of a table of contents plugin that has scrolling active states (your position on the web page will be highlighted or identified in the table of contents structure as you scroll).

Something similar to this website:

[Sticky Table of Contents with Scrolling Active States | CSS-Tricks – CSS-Tricks])

Here is another example which has the table of contents to the left. You can expand the toc and it also highlights where you are on the page:

[How to Read Syntax • Teradata Vantage™ – Teradata® Virtual Storage • Reader • Teradata Online Documentation | Quick access to technical manuals])

Any help would be appreciated.
