I’m trying to define the TOC index items using only the slugs, rather then adding the topic index at the end of the URL - so I can maintain the same TOC index across environments (DEV/PROD).
This appears to work (as it navigates to the correct topic using the slug only), but the current topic is not highlighted in the menu on the left unless I also add the ID to the end of every URL. Is there a workaround for this?
