So, the Frameless output is brilliant. I've started moving over my entire project to it, and I'm loving it. The way it looks is beautiful and smooth - I just have one little issue. When I click on a Topic and it is displayed, the TOC on the left-hand side of the screen displays fine. When I click to other items (books or topics) in the TOC it all responds like it should, in other words, the TOC responds like it should.
However, when I click on a book on the home page, and that book is linked to a topic (source set to a topic), the topic it is set to displays, but the TOC remains closed. On the Responsive HTML5 output, these books are automatically expanded, and it's contents displayed in the TOC, but with the Frameless this doesn't happen. It's not a massive train smash, but ideally if I click on a book and the book's linked source topic is opened, it should expand that book in the TOC so the user can see that there is more to the book than just the single topic.
I've looked around the config and in the skin and layout files, but can't find it. I haven't played around those files as I'm really worried I'll break something, but if someone could help that would be great.
Appreciate the feedback, thanks Sir. I have created the Feature Request. I would LOVE this as it works wonderfully on the other layouts (where it does automatically expand by default). Link to request here: https://tracker.adobe.com/#/view/RH-6583
