Sorry but that's the way it works. You get books and pages. The books contain the pages. If you want topics indented below other topics, you will need to make another book. RoboHelp can help you with this. Right click the page and choose "Create Book from Page" and poof!
Thanks so much for your prompt response Rick. I have only begun working with Robohelp, so I am sure I will have other questions. It’s great to know there is help out there.
