I'm using module Book of Drupal. It's so great.

But I have a lot of books about 3000 books. When I create chapters for books that choose books very difficult because select option very large and performance is slow. enter image description here

Is there any way to simplify this? Eg: convert this select option to autocomplete field,... How do it or any solution?

  • Did you try form alter, alter field book to autocomplete and set value when validation? – Jonh Mar 12 at 9:30
