You have to call a render function recursive for each subtree. As long as there is another subtree it will output another -list.

main_view.php

<?php echo new View('view2',array('node'=>$root_node)) ?>

view2.php

<ul>
    <?php foreach ($node->children() as $child):?>
        <li><?php echo $child->title?></li>
        <?php if ( ! $child->is_leaf()): ?>
            <?php echo new View('view2',array('node'=>$child)) ?>
        <?php endif; ?>
    <?php endforeach; ?>
<ul>

If you also want your HTML intended correct you can use the $node->level() function. But that is really unnecessary
