How do you create a nested book within bookdown?

Within the navigation, bookdown only allows for 3 levels of headings. I am trying to create a book with at least 8 levels. It is very important for even the 8th level to be easily navigated to. I was thinking about solving this solution with a nested book. For example, you have your first book. Then within a page in your first book, you have a link that you click on, that takes you to your second book.

The issue is, since I am creating two books, I would have two index.Rmd files - which doesn't work, since both would be located in same location on github. It would also mean my website would have the same webaddress for two pages. Another issue is, I don't think that when searching in the first book, pages in the second book will show up.

What are some ways to solve the problem of needing more than 3 levels in navigation? Currently I was thinking about nested books but am having trouble figuring out how to do it.

More than three levels of headings are possible. Simply put the following in your YAML.

gitbook:
    toc_depth: 6

However, that doesn't get you to 8, since there are only 6 levels of headers in HTML, I believe.

You could use PART to get to 7. Not sure how you'd get to 8, except by splitting into multiple books.
