We have implemented a patch to inject admin menu into the theme in this showcase.

With this patch, Drupal Administration Menu is output via hook_footer() in

echo $closure;


This effectively means, that you do not need to setup a block for a particular Drupal theme. Furthermore, Drupal Administration Menu does not clutter the (beginning) HTML output with the whole administrative menu structure of a site.

As you can see in this demonstration, Drupal Administration Menu can be implemented without any modifications to a site's theme.¹⁾

However, there are some themes in the wild that do not implement a header region. For many of them, Admin Menu can simply be assigned to another region, for example left sidebar, and a weight of -10.

Unfortunately, there are themes that use deep selectors to force a specific width to blocks in sidebars. In these themes, one may assign Admin Menu to another region, for example content. What matters is that the Admin Menu block is always rendered in front of any other menu block.

¹⁾ Hint: The Drupal Administration Menu banner is injected via JavaScript.
