Creating a menu and linking content

Drupal provides a way to link content being authored to a specified menu on the website, generally the main menu. You can, however, create a custom menu to provide links to content. In this recipe, we will show you how to create a custom menu and link content to it. We will then place the menu as a block on the page, in the sidebar.

Getting ready

This recipe assumes that you have installed the standard installation profile and have the default node content types available for use. You should have some content created to create a link.

How to do it...

  1. Visit Structure and click on Menus.
  2. Click on Add menu.
  3. Provide the title Sidebar and optional summary and then click on Save.
  4. Once the menu is saved, click on the Add link button.
  5. Enter a link title and then type the title for a piece of content. The form will provide autocomplete suggestions for linkable content:
  1. Click on Save to save the menu link.
  2. With the menu link saved, go to Structure, and then Block layout....
