This module improves Drupal's book navigation by allowing users to expand and collapse submenus directly without loading the parent page. It transforms the book navigation into a more dynamic and user-friendly menu system.
Overview
Book Tree Menu enhances the default Drupal Book navigation by transforming it into a more dynamic, user-friendly menu system.
In the standard behavior, users must navigate to a parent page to reveal its child links each submenu only expands when its parent page is visited. This module removes that limitation by allowing users to expand and collapse any submenu directly, without having to load the parent page.
With this enhancement, clicking on a parent item in the left-hand menu will only toggle the visibility of its submenu. It will not navigate to the parent page, which is acceptable since these pages typically serve only as structural containers with no meaningful content beyond Book traversal links.
