I enabled the Book module on drupal 7 and created 2 new content types. Let said I created a new "content type A" and "content type B", and keep the book module content type as "Book page". The issue I have is that whenever I adding a child page on a "Content type A" or the "Content type B" page, these child pages are "Book page" content type. How to keep these child page the same content type as parent page?
PS: I see there is a "Books" setting under "content > books" tab. But it only allow me to select one content type as child page.
