I can't seem to find an answer to the following question. English is not my native language so its sometimes hard to find the right words. I know how to build custom post types but i want to go a level deeper. Within in a custom post type books i want to add pages that should exist as a self existing page. The pages should only be used in one book.
A possible solution i thought: Book as parent, pages as children. But the books overview will be cludded with pages.
Wish: To build a plugin that shows the books like the image below
