Hi, guys.
I'd like to hide the books that user is not allowed to access yet.
I mean, each book is a class. The use is only allowed to access the class #2 if finishes the class #1.
I have more than 6 books/classes. On moodle they stay gray when the uses can't access them, as you can see on my image.
I'd like to really hide them. How can I do this?
