I’m wondering if anyone has had experience adding a custom table of contents that is sticky to the side of the page (almost like a sidebar menu). I want to be able to add this on EVERY page (including home)

I’ve been working on it all week with no luck. I know I need to add a new custom section and also need to reformat the theme.liquid page to be able to view the sticky sidebar table of contents for each page.

Any help or code snippets would be greatly appreciated! Thank you!

This site is a good example of what I want to add:
