不知道在你的代码的一部分，你想补充的是列表，但我已经找到一种方法来显示在子类别的职位列表。

<ul> 
<?php $childCats = get_categories('child_of=6'); 

foreach ($childCats as $childCat) : 
    $this_category = get_category($childCat); 
    $args = array(
    'category__in' => array($childCat->term_id) 
); 
    $childCatPosts = new WP_Query($args); 
    if ($childCatPosts->have_posts()) : ?> 

    <li><?php echo $childCat->name; ?> 

    <?php if ($this_category->category_parent != 0) { ?> 

     <ul> 
     <?php while ($childCatPosts->have_posts()) : $childCatPosts->the_post(); ?> 

      <li><?php the_title(); ?></li> 

     <?php endwhile; ?> 
     </ul> 

    <?php } ?> 
    </li> 

    <?php    
    endif; 
endforeach;  
?> 
</ul>

请注意，'child_of = 6'表示父ID，这将检索类别对象的列表。然后，您需要遍历这些类别并根据子类别ID进行查询。

希望这有助于:)

添加以下代码在主页
