2 comments

1. You can do something like this from server side

   <div id='cssmenu'>
     <ul>
       <li class='active'><a href='#'><span>Home</span></a>
       </li>
   
       <?php query_posts( 'showposts=5&orderby=date&cat=19'); if(have_posts()):?>
       <li class='has-sub'><a href='#'><span>Products</span></a>
         <ul>
           <?php while (have_posts()) : the_post(); ?>
           <a href="<?php the_permalink(); ?>">
             <li>
               <?php the_meta(meta_key); ?>
               <?php the_title(); ?>
             </li>
           </a>
           <?php endwhile; ?>
   
         </ul>
       </li>
       <?php endif;?>
     </ul>
   </div>

   Using jQuery check and filter the empty product item by count of li elements and hide them

   $('.has-sub').filter(function(){
       return $('ul li',this).length == 0;
   }).hide()
   

2. try this,

   <?php query_posts('showposts=5&orderby=date&cat=19'); ?>
   <?php if(have_posts()) { //       <------ check before entering while.
            while (have_posts()) : the_post(); ?>
               <a href="<?php the_permalink(); ?>" ><li><?php the_meta(meta_key); ?><?php the_title(); ?> </li></a>
   <?php } endwhile; ?>
