Render an administrative menu as a dropdown menu at the top of the window.

Code

function admin_menu_admin_menu_output_build(&$content) {
  if (!isset($content['menu'])) {
    return;
  }

  // Unassign weights for categories below Configuration.
  // An alphabetical order is more natural for a dropdown menu.
