RH2019 How do you keep entire TOC tree when expanding a folder?

[#1]

I am using RoboHelp 2019 and generating Responsive HTML5 output. My TOC consists of multiple folders with topics under each folder.

When I generate the TOC, I see the folders, but when I expand one folder, the entire TOC tree disappears and I only see the folder/topics I have expanded.  

Is is possible to keep the entire TOC tree when expanding a single folder?  (This is the case when generating a CHM.)

Which skin? They don't all work the same way.

2019 Classic or New UI?

RoboHelp 2019 Classic

Responsive HTML5 - Axure_Blue (RTL) skin

I also don't see any properties for the TOC as whole (expand all/ collapse all, etc.)

[#5]

In the Gallery for Classic there is no Azure Blue RTL. It is a 2019 New UI skin only. Using the camera icon please add a screenshot showing the list of screens available in Gallery in Classic.

If you are trying to use a 2019 New UI skin in a Classic project, it is not going to work.

Then, it looks like I am in the new UI. I can't find any properties to control the TOC. I can only access 'Page' properties...see screen shot. How do I control the TOC to display an expanded tree when it generates Responsive HTML5 with the Azure skin?

Could I control the TOC properties if I was in the Classic UI?

Are you talking about the TOC when editing or the TOC the user sees?

If when editing, in the left panel you can only expand one at a time. If you want to see multiple TOCs, open them in the authoring area. Double click the TOCs you want in the left panel.

This is explained in the supplied RoboHelp Reimagined sample project. As you are seem to be new to 2019 New UI, it would be worth going throught that as it explains a lot about the new UI.

If you are talking about what the user sees, I just tested a RTL and once a book is expanded, it stays expanded even when others are opened.
