How to hide sections under docs layout in sidebar navigation

[AbdulSayyed]

I need to know if there is any way, only one section under the docs folder or any folder that is using type: docs or layout: docs settings, can be shown in the docs sidebar instead of all sections appearing. Let me explore it more clearly below
In my HBStack site, I’ve moved my courses' contents into the courses folder, so they render with the docs layout. Under ibm I now have four course sections/folders (e.g. devops-pcert, fullstack-pcert, ml-pcert, ibm-ai-developer-pcert). When I open /courses/ibm/, the docs navigation on left sidebar lists all four sections. How can I configure so the docs sidebar only exposes one designated course section—say /courses/ibm/devops-pcert/—while the other sections remain reachable by direct URL but stay hidden from the default nav? Is there an official pattern for scoping the docs navigation to a single child section?”

If I understand correctly, you can specify the docs_root_section page parameter as false on first section's frontmatter, content/courses/_index.md in your case. Then /courses/ibm/ will list content under /courses/ibm/ folder rather than /courses
