这只是一个快速的问题，有没有人知道一个jQuery插件，它可以复制WordPress菜单创建器的相同操作，即您可以拖放菜单项，还可以稍微向右拖动以缩进作为上面链接的子菜单？我已经到处寻找了（我知道它是使用jquery UI制作的），但找不到任何将其封装成插件的人。

<li id="post-id-2" child="2" parent="0" class="ui-state-default posty">Test 2</li>
<li id="post-id-5" child="5" parent="0" class="ui-state-default posty">Test 3</li>
<li id="post-id-3" child="3" parent="0" class="ui-state-default posty">Test 4</li>
<li id="post-id-4" child="4" parent="0" class="ui-state-default posty">Test 5</li>
</ul>
(and I know it's made using the jquery UI) but cant find anyone who has wrapped it up into a plugin.- Phil Jackson
