WordPress can be used as CMS. So, I think I can switch from Drupal to WordPress.
I’m looking for a book module alternative for creating structured document.
If you don’t know about Book module of Drupal, follow this link: http://drupal.org/documentation/modules/book
It simply put all page links in navigational block maintaining the hierarchical sequence. Plus, it displays next & previous pages in sequence at bottom with their respective links. The book module documentation at previous link is also an example of Book module page.
Is there any WordPress alternative to Book module of Drupal?
With a hierarchical post type, a plugin would just need to write the navigation part. All the rest is already there.
I haven’t tried this. I’m about to. It looks quite promising:
