Non-scripture book in 2nd pane

We have a set of general study questions that we would like to have open in a second pane while the scripture text is open in the first pane. I have added the questions as a book. When I choose the questions book in two pane layout, only a gray block is displayed. If I make the questions the first choice and the scripture the second, the scripture is only a gray block. Is there a way to show both books in two-pane layout?

There is a feature called tabs that allow the user to see related questions to scripture. See section 17 in Building Apps documentation.

I will experiment with Tabs. From the documentation, it appears you either have the tab displayed, or the text displayed. Can both be open at once?

I think you are correct that it is one or the other with tabs.
