Nested menus/section links CMS integration

Hi, I’m beginning to plan a site to host our API documentation. We’d like to use the CMS if at all possible to make it easy to manage, but I need some help conceptualising the structure of how to build this page inside webflow.

Here’s the idea:
We have a left navbar with headings, subheadings, and items, all as accordion-type nested lists. Ideally I’d like to have these all generated from cms items. I am willing to have each category or subcategory as a different page, but ideally, I’d like to populate it all on one page but still managed as individual items in the CMS.

concept structure:
left Navbar:

  • Heading
    • Subheading 1
    • Subheading 2
    • Subheading 3
      • Item 1
      • Item 2
      • Item 3
  • Heading 2 (etc etc.)

functionally similar to this page:

Any ideas on how I can structure this best?

Ideally we would have the links all just “jump” the the appropriate section on the page rather than reloading the page.

Cheers.
Simon

PS I’ll add that this is just one page (or part of the site) on our entire support site - Thought I should make it clearer
