菜单在wordpress中不是动态的

Question

我使用的是我们的wordpress代码：

<?php 
    echo wp_nav_menu(array(
    'menu' => '',
    'container' => 'div',
    'container_class' => '', //container class
    'container_id' => '',   // it is our container id
    'menu_class' => 'nav navbar-nav navbar-right', //our menu classs
    'menu_id' => '',
    'echo' => true,
    'fallback_cb' => 'wp_page_menu',
    'before' => '',
    'after' => '',
    'link_before' => '',
    'link_after' => '',
    'items_wrap' => '<ul id="%1$s" class="%2$s">%3$s</ul>',
    'depth' => 0,
    'walker' => '',
    'theme_location' => ''
));?>

这是HTML代码：

<ul class="nav navbar-nav navbar-right">
<li class="dropdown">
    <a class="dropdown-toggle" data-toggle="dropdown"   href="#">TOUR PACKAGES
        <span class="caret"></span>
    </a>
    <ul class="dropdown-menu">
      <li><a href="#">1</a></li>
      <li><a href="#">2</a></li>
      <li><a href="#">3</a></li>
    </ul>
</li>
<li class="dropdown">
    <a class="dropdown-toggle" data-toggle="dropdown"   href="#">DESTINATION
        <span class="caret"></span>
    </a>
    <ul class="dropdown-menu">
      <li><a href="#">1</a></li>
      <li><a href="#">2</a></li>
      <li><a href="#">3</a></li>
    </ul>
</li>
<li><a href="#">OUR CABS</a></li>
<li><a href="#">CONTACT US</a></li>
<li class="contact-btn"><a class="btn-lg" href="#">HONEYMOON PACKAGE<span class="sprite pack-btn"></span></a></li>
