Question: how to show all headers in left-side sidebar?

[linrongbin16]

The h1 and h2 level headers are shown in left side sidebar. But h3 h4 are not shown.

Is there a way to allow show them all?

Perhaps it may work if you add the toc extension and define a toc_depth here:

markdown_extensions:
  - toc:
      toc_depth: 3

The number sets the lowest header level to include, which in my example would be h1 to and with h3
