在Wordpress循环中展开的复选框

我为Wordpress循环创建了自己的风格，它在Bootstrap脚手架中显示了最近10篇文章的图像。

每个图像都有一个标签，您可以单击以展开信息。但是，无论您单击哪个复选框，它都只会打开和关闭循环中的第一个帖子。

我已经尝试将li和子li值分配给css，并将复选框标签进一步移动到循环中。到目前为止没有任何帮助。我确信这与这样一个事实有关，因为它是循环的，我不能将每个复选框分配给特定的帖子。只有一个〔for＝"check"〕

这个复选框的想法可行吗？

HTML:

<li class="<?php echo $span; ?>">
    
      <?php
echo '<div class="postexpander"><label for="check"><div class="postarrow"> <p>Expand Info <span class="glyphicon glyphicon-plus"></span></p></div></label>';
echo '<input id="check" type="checkbox">';
echo '<div class="posttext" onclick="posttext:hover">';
echo '<p class="posthead">';
echo '<a href="' . get_permalink( $thumbnail->ID ) . '" title="' . esc_attr( $thumbnail->post_title ) . '">'; 
the_title();
echo '</a>';
echo '</p><p class="postdate">';
the_date('F jS, Y');
echo '</p><p class="postcontent">';
$content = get_the_content();
$trimmed_content = wp_trim_words( $content, 15,"...".'<p class="readmore"> <a href="'. get_permalink() .'">Read More</a>' );
echo $trimmed_content;
echo '</p>';
echo '</div></div>';
if(has_post_thumbnail()) {                    
$image_src = the_post_thumbnail( 'custom-size', array( 'class' => "postimage" ) );
    echo '<a href="' . get_permalink( $thumbnail->ID ) . '" title="' . esc_attr( $thumbnail->post_title ) . '">';
    echo '</a>';}?> 
</li>    
<?php
 //End the post loop
 endwhile; else:
?>

CSS：

在图片中，你可以看到，即使我点击了信息选项卡（悬停时为浅蓝色），它也会扩展上面帖子上的文本。
