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

Code

function admin_menu_menu_alter(&$items) {
  foreach ($items as $path => $item) {
    if (!strncmp($path, 'admin/', 6)) {
      if (isset($item['type'])) {

        // For any reason, content-type menu items are registered individually
        // in Drupal core, but also by CCK. We a) have to copy and re-assign
        // them the proper router path and b) turn their parent items from
        // MENU_CALLBACK into something visible; otherwise, the menu system
        // does not find the parents and relocates child items to the top-level.
        if (strpos($path, 'admin/content/node-type/') === 0) {

          // Copy item with fixed router path.
          $newpath = str_replace('/node-type/', '/types/', $path);
          $items[$newpath] = $item;

          // Use new item from here, but leave old intact to play nice with
          // others.
          $path = $newpath;

          // Turn MENU_CALLBACK items into visible menu items.
          if ($item['type'] == MENU_CALLBACK) {

          }
        }

        // Skip invisible MENU_CALLBACKs.
        if ($item['type'] == MENU_CALLBACK) {
          continue;
        }

        // Trick local tasks and actions into the visible menu tree.
        if ($item['type'] & MENU_IS_LOCAL_TASK) {
          $items[$path]['_visible'] = TRUE;
        }
        $items[$path]['menu_name'] = 'admin_menu';
      }
    }
  }

  // Remove 'admin', so children appear on the top-level.
  $items['admin']['menu_name'] = 'admin_menu';

  // Remove local tasks on 'admin'.
  $items['admin/by-task']['_visible'] = FALSE;
  $items['admin/by-module']['_visible'] = FALSE;

  // menu_link_save() looks up the parent's menu_name directly in the database
  // instead of taking data in hook_menu() into account. When installing
  // admin_menu, {menu_links} contains the default value of 'navigation', which
  // is thereby applied to all items, even if this function altered them. There
  // is no other way to override this behavior.
  // Additionally, if links below admin/ were moved or customized in any way and
  // those are moved back into the administration menu, then the menu system
  // will not calculate/assign the proper menu link parents when the parent item
  // (here: 'admin') is marked as customized.
  db_query("UPDATE {menu_links} SET menu_name = 'admin_menu', customized = 0 WHERE router_path = 'admin'");

  // Flush client-side caches whenever the menu is rebuilt.
  admin_menu_flush_caches();
