Answer 1

You could try this, it's not elegant but should work:

    <ul id="menu">
    <?php foreach ($categories as $category) : 
        echo '<li><a href="'.$category['href'].'">'.$category['name'].'</a>';
        if (!empty($category['children'])) : 
            echo '<ul>';
            foreach ($category['children'] as $category_level2) :
                echo '<li><a href="'.$category_level2['href'].'">'.$category_level2['name'].'</a>';
                if (!empty($category_level2['children'])) :
                    echo '<ul>';
                    foreach ($category_level2['children'] as $category_level3) :
                        echo '<li><a href="'.$category_level3['href'].'">'.$category_level3['name'].'</a></li>';
                    endforeach;
                    echo '</ul>';
                endif;
                echo '</li>';
            endforeach;
            echo '</ul>';
        endif;
        echo '</li>';
    endforeach;
    echo '</ul>';
    ?>
