Hello.
How to hide the 1.1.1. Test3 section from the contents without deleting the numbering. I read the documentation and found nothing.
I need to do as in screenshots 2 and 3
I understand you need to remove level 3 sections and below from generated toc. However, by default only level 1 and 2 are show (see 'toclevels' https://asciidoctor.org/docs/user-manual/#user-toc-levels).
That means that either the previewer or the build process you are using is interfering.
