Drupal comes with a toolbar which is useful when administering a Drupal site. If you log in and have the correct permissions, you’ll see a toolbar across the top of the page that allows you to access back-end configuration pages.
The Admin Toolbar module extends the functionality of the toolbar and gives you lots of extra features such as drop-down menus, access to cache and cron settings and an autocomplete search.
In this tutorial, you will learn how to install and configure Admin Toolbar and its sub-modules.
