This is especially important with responsive designs where mobile layouts do not have drop-down menus. Of course WordPress has an easy answer.
// add this to page.php

$children = wp_list_pages(‘title_li=&child_of=’.$post->ID.’&echo=0′);
if ($children) { ?>
<div class=”widget widget_pages jsmenu jswidget”><ul>
<?php echo $children; ?>
</ul></div>
<?php } ?>
