 'dropdown_categories' function in wp-admin/includes/template.php returns
 invalid html list
 {{{
 <ul>
  <li>a</li>
  <li>b</li>
  <ul>
   <li>b-1</li>
   <li>b-2</li>
  </ul>
 <li>c</li>
 </ul>
 }}}

 It should be
 {{{
 <ul>
  <li>a</li>
  <li>b
  <ul>
   <li>b-1</li>
   <li>b-2</li>
  </ul>
  </li>
 <li>c</li>
 </ul>
 }}}

 We just need to print '</li>' after child list if a category has children.
 {{{
 function write_nested_categories( $categories ) {
         foreach ( $categories as $category ) {
                 echo '<li id="category-', $category['cat_ID'], '"><label
 for="in-category-', $category['cat_ID'], '" class="selectit"><input
 value="', $category['cat_ID'], '" type="checkbox" name="post_category[]"
 id="in-category-', $category['cat_ID'], '"', ($category['checked'] ? '
 checked="checked"' : "" ), '/> ', wp_specialchars(
 apply_filters('the_category', $category['cat_name'] )), "</label>";

                 if ( $category['children'] ) {
                         echo "<ul>\n";
                         write_nested_categories( $category['children'] );
                         echo "</ul>\n";
                 }
                 echo "</li>";
         }
 }
 }}}


 It displayed well on blog, but while I was trying to make 'AJAX category
 adder for specific parent category', it matters.
