How can I keep TOC (drill-down) full view in different Desktop resolutions in RH HTML5 2015? I have tried changing resolution, but it doesn't work. It seems something has to do with the TOC itslef

- In 1st image (90% zoom), the topics are all displayed and you can navigate through with keeping the full view

- In 2nd Image, (100% zoom), clicking any topic takes you from the full view to the sub-topics.

I need to keep Image 1 view in different Desktop zooming..Any advice?
