Menu Block gives you additional functionality around managing the display of menus in block regions. Drupal core allows you to add any menu such as main navigation, footer, etc… into any region and you can control how many menu levels should be displayed. Menu Block gives you additional options such as setting a fixed parent item, changing the block title, and more.

But the one feature of Menu Block I want to show you in this tutorial is the ability to add a custom theme hook suggestion to menus.
