我正在努力实现这样的目标：

A:

父类别以

子类别另一个父类别，以

子类别B:

父类别以B开头

子类别子类别。。。等

我很难找到这样的插件，我找到的插件不是很好。我也不能自己编写代码，因为我只有有限的PHP知识。

但我确实遇到了以下片段：

$list = \'\';
$cats = get_terms(\'category\');
$groups = array();
if( $cats && is_array( $cats ) ) {
    foreach( $cats as $cat ) {
        $first_letter = strtoupper( $cat->name[0] );
        $groups[ $first_letter ][] = $cat;
    }
        if( !empty( $groups ) ) {
            {
            $index_row .=\'<ul>\';

                foreach ($groups as $letter => $cats) {
                    $index_row .= \'<li><h4><a href="#\' . $letter . \'" title="\' . $letter . \'">\' . apply_filters( \'the_title\', $letter ) . \'</a></h4></li>\';
                    }

            $index_row .=\'</ul>\';
            } //Index Row End 

            foreach( $groups as $letter => $cats ) 
            {
                $list .= \'<div class="asset-cata clearfix">\' . "\\n";
                $list .= \'<div class="letter">\' . "\\n";
                $list .= \'<h1>\' . apply_filters( \'the_title\', $letter ) . \'</h1>\' . "\\n"; // The Letters On Their Own
                $list .= \'</div>\' . "\\n";

                $list .= \'<div class="list-items">\' . "\\n";
                $list .= \'<ul>\' . "\\n";

                    foreach( $cats as $cat ) 
                    {

                        $url = attribute_escape( get_category_link( $cat->term_id ) );
                        $name = apply_filters( \'the_title\', $cat->name );

                        $list .= \'<li class="item">\' . "\\n";
                        $list .= \'<a title="\' . $name . \'" href="\' . $url . \'">\' . $name . "\\n";


                                    $list .= \'<span class="number">\'. $cat->count .\'</span> \' . "\\n";

                        $list .= \'</a>\' . "\\n";
                        $list .= \'</li>\' . "\\n";
                    } 

                $list .= \'</ul>\';
                $list .= \'</div>\';
                $list .= \'</div>\';
            }   

    } // GRoups End
} else 
$list .= \'<p>Sorry, but no cats were found</p>\';

这在一定程度上实现了我的愿望，但并没有把孩子的类别与他们的父母放在一起，这正是我想要实现的
