CSS Dropdown menu for the header- With Categories!

[darkswan]

Few things to check:
Do you have LEFT/RIGHT status set to OFF, SINGLE COLUMN status set to ON?

Yes

Does your information section in includes/templates/YOUR_TEMPLATE/common/tpl_drop_menu.php look like this:

<li class="submenu"><a href="<?php echo zen_href_link(FILENAME_DEFAULT); ?>"><?php echo HEADER_TITLE_INFORMATION; ?></a>
        <ul class="level2">
          <li><a href="<?php echo zen_href_link(FILENAME_SHIPPING); ?>"><?php echo HEADER_TITLE_SHIPPING_INFO; ?></a></li>
          <li><a href="<?php echo zen_href_link(FILENAME_PRIVACY); ?>"><?php echo HEADER_TITLE_PRIVACY_POLICY; ?></a></li>
          <li><a href="<?php echo zen_href_link(FILENAME_CONDITIONS); ?>"><?php echo HEADER_TITLE_CONDITIONS_OF_USE; ?></a></li>
          <li><a href="<?php echo zen_href_link(FILENAME_ABOUT_US); ?>"><?php echo HEADER_TITLE_ABOUT_US; ?></a></li>
          <?php if (defined('FILENAME_SITE_MAP')) { ?>
          <li><a href="<?php echo zen_href_link(FILENAME_SITE_MAP); ?>"><?php echo HEADER_TITLE_SITE_MAP; ?></a></li>
          <?php } ?>
          <?php if (MODULE_ORDER_TOTAL_GV_STATUS == 'true') { ?>
          <li><a href="<?php echo zen_href_link(FILENAME_GV_FAQ, '', 'NONSSL'); ?>"><?php echo HEADER_TITLE_GV_FAQ; ?></a></li>
		  <?php } ?>
          <li><a href="<?php echo zen_href_link(FILENAME_DISCOUNT_COUPON, '', 'NONSSL'); ?>"><?php echo HEADER_TITLE_DISCOUNT_COUPON; ?></a></li>
		  <?php if (SHOW_NEWSLETTER_UNSUBSCRIBE_LINK == 'true') { ?>
          <li><a href="<?php echo zen_href_link(FILENAME_UNSUBSCRIBE, '', 'NONSSL'); ?>"><?php echo HEADER_TITLE_UNSUBSCRIBE; ?></a></li>
		  <?php } ?>
		  <?php require(DIR_WS_MODULES . 'sideboxes/' . $template_dir . '/' . 'ezpages_drop_menu.php'); ?>
        </ul>
      </li>

No. The ezpage callout is in the HOME submenu. However even when it is moved to the block you listed, it still breaks. I have updated it to reflect the code listed above and now the menu breaks at teh INFORMATION submenu.
