当我们使用显示菜单时wp_nav_menu, 它创建的菜单结构如下：

<div class="container">
  <ul class="list">
    <li class="item">
      <a class="link" href="#">Link 1</a>
    </li>
    <li class="item">
      <a class="link" href="#">Link 2</a>
    </li>
    <li class="item">
      <a class="link" href="#">Link 3</a>
    </li>
    <li class="item">
      <a class="link" href="#">Link 4</a>
    </li>
    <li class="item">
      <a class="link" href="#">Link 5</a>
    </li>
  </ul>
</div>

我如何才能将其更改为这样：

<div class="container">
  <a href="#">Item 1</a>
  <a href="#">Item 2</a>
  <a href="#">Item 3</a>
  <a href="#">Item 4</a>
  <a href="#">Item 5</a>
</div>

我试图通过过滤器对其进行自定义，但我无法通过参数检查菜单，参数只是为空。

我的代码如下：

// page.php
wp_nav_menu([ \'theme_location\' => \'sidebar_menu\' ]);

// functions.php
function custom_menu($items, $args) {
    // ....
    print_r($args); // NULL
}

apply_filter(\'wp_nav_menu\', \'custom_menu\');

add_filter( \'wp_nav_menu\', function( $nav_menu, $args ) {
  if( \'my_custom_menu\' == $args->menu->slug ) {
    // include a template with your required markup
    // reference both the $nav_menu and $args params in the template
    return include(\'my-nav-template.php\');
  } else {
    return $nav_menu;
  }
}, 10, 2);
