Chapter 5: Menus and Menu Links

Navigation is an important part of any web application. The ability to create menus and links easily in order to connect pages together is a core aspect of any content management system. Drupal is fully equipped with both the site-building capabilities and developer API to easily build and manipulate menus and links.

In this chapter, we will discuss menus and menu links from a Drupal 9 module developer perspective. In doing so, we will touch upon a few key aspects:
