Child menu items not displayed in drupal

Question

I've a sub-menu like this:

I'm trying to build a custom theme, I just copied which contains following code:

<?php if ($main_menu || $secondary_menu): ?>
  <div id="navigation"><div class="section">
    <?php print theme('links__system_main_menu', array('links' => $main_menu, 'attributes' => array('id' => 'main-menu', 'class' => array('links', 'inline', 'clearfix')), 'heading' => t('Main menu'))); ?>
    <?php print theme('links__system_secondary_menu', array('links' => $secondary_menu, 'attributes' => array('id' => 'secondary-menu', 'class' => array('links', 'inline', 'clearfix')), 'heading' => t('Secondary menu'))); ?>
  </div></div> <!-- /.section, /#navigation -->
<?php endif; ?>

This is how its being displayed: Note that not even the HTML for child menu items are generated.

Yes, I've Show as expanded option checked for "Publications".

PS: Why does drupal make even such simple things difficult. No wonder, its losing ground to wordpress.

Answer 1

Try this:

<?php
$menu_name = variable_get('menu_main_links_source', 'main-menu');
$tree = menu_tree($menu_name);
print drupal_render($tree);
?>

Also Drupal doesn't make things hard, you just don't understand it yet.

It is just a tool suited to specific tasks. If you just want to make a blog then don't use Drupal, just use Wordpress.

If however you want a very powerful CMF (Content management framework, not system) to create complex systems with lots of inter-related entities then continue to learn Drupal - I think it's the best tool for the job.
