Is there a way to display all sub wikis in an index page in gitlab?

So in gitlab you can use [[_TOC_]] to display a table of contents for the current page - which works on headings.

But I want to have a heirachy in my wiki like:

<home-url>/Project1
<home-url>/Project1/Tools
<home-url>/Project1/Debugging
<home-url>/Project1/Debugging/GDB
<home-url>/Project1/Debugging/MSVS

Such that in the Project1 page I get an index (links) to each section similar to the table of contents layyout - e.g.:

 - Tools
 - Debugging
    - GDB
    - MSVS

I can do this manually, but that's a pain to maintain. Is there some automatic tool to do this for me like TOC?

Solution

The TOC support steams from issue 2494, and was implemented in issue 21901, which gave us the Markdown [[_TOC_]] syntax.

Even the current request to support [TOC] instead (issue 14193) does not mention any layout option to include a hierarchical display.

As mentioned in the first issue:

If you need more control, you can open a new issue at https://gitlab.com/gitlab-org/gitlab/issues and upvote it.

For example: issue 215988: "Add Gollum depth level support for Wikis Table of Contents [[_TOC_]]"

Having the ability to limit a [[TOC]] depth is useful to show a more synthetic view of a page while keeping its deeply nested structure.
