How to disable admin flyout menus?

3 comments

1. It’s a bit of a workarround but here you go:

   function remove_flyout() {
      echo '<style type="text/css">
           .js #adminmenu .wp-submenu.sub-open {
               display: none;
           }
       </style>';
   }
   add_action('admin_head', 'remove_flyout');
   

   Put it in your functions.php

2. Aaron Campbell wrote a gist to expand all menus all the time. The dev chat today also indicated some issues in the blue theme.

   For more discussion, see Admin menu doesn’t expand/collapse in 3.3 beta 1. Why? in the Support forums.

3. The solution provided is not working in modern version, but I’ve finally found how to fix it in a new one, just add

   #adminmenuwrap {
   overflow: hidden;
   }
   

   via custom css plugin or browser add-on and flyouts both on :hover and :active will be hidden
