请在下面找到显示导航菜单的功能。在这里$menu 相当于Menu name, ID, or slug

<?php 
function showMyMenu($menu)
{
    $navData = wp_get_nav_menu_items($menu); 
?>
<ul class="nav navbar-nav navbar-right is-hidden">
    <?php
    foreach($navData as $k => $v)
    {   
        echo \'<li><a class="page-link" href="\' . $v->url . \'"> \' . $v->title . \' </a></li>\';
    }
    ?>
</ul>
<?php } ?>
