title: Wordpress add submenus to custom menu
body: <p>In a wordpress plugin I'm creating, it's creating a new top-level admin menu with a sub-menu page. Here's my code:  </p>
  
  <pre><code>add_menu_page('Eastview Custom', 'Eastview Custom', 5,"eastview-custom");
  add_submenu_page("eastview-custom","GLS Lunch Orders","GLS Lunch",5,'glsLunch','glsLunch');
  </code></pre>
  
  <p>So this code creates a new admin menu, "Eastview Custom". Then it adds two sublinks: "Eastview Custom" and "GLS Lunch". The problem is that I don't want "Eastview Custom" as a sublink. I would like the only sublink to be "GLS Lunch". I can't figure out how to do this. Thanks for any help!</p>
