wordpress 调用指定栏目下面的子栏目 自定义div样式

<?php
$args=array(
'type' => 'post',
'child_of'=> $catid01,
'parent' => $catid01,
'orderby' => 'ID',
'order' => 'ASC',
'hide_empty'=>'0',
'hierarchical' => 1,
'exclude' => '',
'include' => '',
'number' => '',
'pad_counts' => false
);
$categories=get_categories($args);
$r=1;
foreach($categories as $category) {?>
<li><a href="<?php echo get_category_link( $category->term_id );?>"><?php echo $category->name;?></a></li>
<?php $r++;
if($r>15)
break;
}
?>

$catid01 是需要调用的 栏目id
