Documentation Request: Include subsection links in documentation sidebar

[DanKaplanSES]

For context, I was trying to learn the difference between = and |=. The sidebar includes Assignment but it does not include links to the subsection named Update assignment: |= or Plain assignment: =. Because another section divides these two, I had to scroll back and forth to read, and often went clicked on the wrong place by clicking on Advanced Features instead of "Assignment."

To put it another way, I would like another level of nesting for each section so, for example, there would be links for "Update assignment" and "Plain assignment" at this red line:

Environment (please complete the following information):

• OS and Version: [e.g. macOS, Windows, Linux (please specify distro)]: Windows 10, WSL Ubuntu
• jq version [e.g. 1.5]: 1.6

Had a quick look at adding a subsection for each entry for a section in the content tree. Ran into two issues:

• Some section has quite a lot of entries, might make the table of contents quite long. Maybe could be solved by folding somehow? see below
• Didn't find any clear way with bootstrap to generate a "tree" table of contents that still shows the "active" section when scrolling. Someone who knows bootstrap maybe knows how?

A possible other solution might be to move out some entries to become sections instead?
