With the Toolbar Menu module, you can add as many menus as you need to the toolbar of your Drupal installation. By default, a Drupal 8 installation has 3 menu links in its toolbar.

1. Manage - Administration of the whole Drupal site, 2. Shortcuts - Links added by the admin to administrative pages used frequently, 3. User Name - Link to the profile page

This module works also with the Admin Toolbar module, which improves the default toolbar providing dropdown menus. In this tutorial, we’re going to cover the usage of the Toolbar Menu module.
