我一直在尝试将HTML菜单添加到WordPress转换主题中，我已经完成了header.php，footer.php和index.php的所有操作。现在在我的header.php文件中，我有菜单，但是由于结构的添加方式非常不同，我感到困惑。我的“ header.php”文件中，我通过Pinegrow主题转换器添加了菜单
<header class="header-area">

</header> [我还尝试通过在左上角的屏幕选项中启用类选项来在Wordpress中创建菜单时，向菜单中添加类。
预期结果are this
以及我得到的最终结果（成功创建了菜单，但是尝试添加下拉列表this happens时]
添加或更新主题中的任何wp_nav_menu（）函数（通常在header.php中找到），通过在wp_nav_menu args数组中添加“ walker”项来使用新的walker。
wp_nav_menu( array( 'theme_location' => 'primary', 'depth' => 2, // 1 = no dropdowns, 2 = with dropdowns. 'container' => 'div', 'container_class' => 'collapse navbar-collapse', 'container_id' => 'bs-example-navbar-collapse-1', 'menu_class' => 'navbar-nav mr-auto', 'fallback_cb' => 'WP_Bootstrap_Navwalker::fallback', 'walker' => new WP_Bootstrap_Navwalker(), ) );您的菜单现在将使用正确的语法和类进行格式化，以实现Bootstrap下拉导航。
通常，菜单包装有其他标记，这是一个固定顶部菜单的示例，该菜单可以折叠以在md断点处进行响应式导航。
<nav class="navbar navbar-expand-md navbar-light bg-light" role="navigation">
<div class="container">
<!-- Brand and toggle get grouped for better mobile display -->
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-controls="bs-example-navbar-collapse-1" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<a class="navbar-brand" href="#">Navbar</a>
<?php
wp_nav_menu( array(
'theme_location' => 'primary',
'depth' => 2,
'container' => 'div',
'container_class' => 'collapse navbar-collapse',
'container_id' => 'bs-example-navbar-collapse-1',
'menu_class' => 'nav navbar-nav',
'fallback_cb' => 'WP_Bootstrap_Navwalker::fallback',
'walker' => new WP_Bootstrap_Navwalker(),
) );
