将Bootstrap导航栏转换为WordPress菜单

Question

我知道网上有很多这方面的话题,但我发现它们非常复杂.基本上我想将Bootstrap导航菜单转换为WordPress菜单.

假设我有默认的Bootstrap Navbar:

<nav class="navbar navbar-default" role="navigation">
  <div class="container-fluid">
    <!-- Brand and toggle get grouped for better mobile display -->
    <div class="navbar-header">
      <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1">
        <span class="sr-only">Toggle navigation</span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
      </button>
      <a class="navbar-brand" href="#">Brand</a>
    </div>

    <!-- Collect the nav links, forms, and other content for toggling -->
    <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
      <ul class="nav navbar-nav">
        <li class="active"><a href="#">Link</a></li>
        <li><a href="#">Link</a></li>
        <li class="dropdown">
          <a href="#" class="dropdown-toggle" data-toggle="dropdown">Dropdown <span class="caret"></span></a>
          <ul class="dropdown-menu" role="menu">
            <li><a href="#">Action</a></li>
            <li><a href="#">Another action</a></li>
            <li><a href="#">Something else here</a></li>
            <li class="divider"></li>
            <li><a href="#">Separated link</a></li>
            <li class="divider"></li>
            <li><a href="#">One more separated link</a></li>
          </ul>
        </li>
      </ul>
      <ul class="nav navbar-nav navbar-right">
        <li><a href="#">Link</a></li>
        <li class="dropdown">
          <a href="#" class="dropdown-toggle" data-toggle="dropdown">Dropdown <span class="caret"></span></a>
          <ul class="dropdown-menu" role="menu">
            <li><a href="#">Action</a></li>
            <li><a href="#">Another action</a></li>
            <li><a href="#">Something else here</a></li>
            <li class="divider"></li>
            <li><a href="#">Separated link</a></li>
          </ul>
        </li>
      </ul>
    </div><!-- /.navbar-collapse -->
  </div><!-- /.container-fluid -->
</nav>

我通常将此导航栏与我的WordPress页面链接的方式不是手动列出每个<li>我将使用以下内容:

    <ul class="nav navbar-nav">
     <?php wp_list_pages('title_li=');?>
     </ul>

这个输出会列出我在WordPress中创建的所有页面:

 <ul class="nav navbar-nav">
    <li class="page_item page-item-9"><a href="...">About</a></li>
    <li class="page_item page-item-2"><a href="...">Sample Page</a></li>
  </ul>

这很好,因为我可以添加一个页面,它按预期包含在我的菜单中.

问题

问题是我不知道如何在菜单栏中包含一个下拉项并将其集成到WordPress中,例如下拉项:

<li class="dropdown">
    <a href="#" class="dropdown-toggle" data-toggle="dropdown">Dropdown <span class="caret"></span></a>
     <ul class="dropdown-menu" role="menu">
            <li><a href="#">Action</a></li>
            <li><a href="#">Another action</a></li>
            <li><a href="#">Something else here</a></li>
            <li class="divider"></li>
            <li><a href="#">Separated link</a></li>
            <li class="divider"></li>
            <li><a href="#">One more separated link</a></li>
     </ul>
  </li>

我将如何与WordPress等下次再整合,如果我想添加一个新的下拉列表,我可以轻松地做同样的方式与正常的菜单项？

如果你不提供WordPress codex网站和其他教程的链接,我会很感激,因为我已经尝试了很多东西

您需要使用此https://github.com/twittem/wp-bootstrap-navwalker,添加nav walker文件并按照说明操作.以下是我制作的随机网站的示例,我不会将其调整到您自己的网站,因为您需要了解所有未来的WP开发.这很简单,请查看:

    <div id="nav">
    <nav class="navbar navbar-default navbar-fixed-top" role="navigation">
      <div class="container">
        <!-- Brand and toggle get grouped for better mobile display -->
        <div class="navbar-header">
          <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
            <span class="sr-only">Toggle navigation</span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
          </button>
          <a class="navbar-brand" href="<?php bloginfo('url'); ?>"><img class="logo" src="<?php bloginfo('template_directory'); ?>/images/logo.png" alt="" /></a>
        </div>


        <?php
        wp_nav_menu( array(
                'menu'              => 'primary',
                'depth'             => 2,
                'container'         => 'div',
                'container_class'   => 'navbar-collapse collapse',
                'menu_class'        => 'nav navbar-nav',
                'fallback_cb'       => 'wp_bootstrap_navwalker::fallback',
                'walker'            => new wp_bootstrap_navwalker())
            );
        ?>
      </div><!-- /.container-fluid -->
    </nav>
</div><!-- #nav -->

您可能已经注意到,基本上您必须替换代码之后的内容

 <!-- Collect the nav links, forms, and other content for toggling -->

同

<?php
    wp_nav_menu( array(
            'menu'              => 'primary',
            'depth'             => 2,
            'container'         => 'div',
            'container_class'   => 'navbar-collapse collapse',
            'menu_class'        => 'nav navbar-nav',
            'fallback_cb'       => 'wp_bootstrap_navwalker::fallback',
            'walker'            => new wp_bootstrap_navwalker())
        );
    ?>
