Print the secondary links as expanded in a template file
In your themes template.php add the following:

function THEMENAME_preprocess_page(&amp;$variables) {

  // Get the entire menu tree (you can replace this string with any menu you want)
  $main_menu_tree = menu_tree_all_data('main-menu');

  // Generate structure for rendering the menu.
  $menu = menu_tree_output($tree);

  // Replace the $menu array with the #below array beloning to the first top 
  // level menu item.
  $menu = $menu[key($menu)]['#below'];

  // Add $main_menu_no_top as a variable to use in our theme
  $variables['main_menu_no_top'] = $menu;
}


Then, in page.tpl.php, you can just use:

&lt;?php print render($main_menu_no_top); ?&gt;
