我很难过。我一直在试图解决这个问题2天，并在网上查找包括本网站在内的所有内容。这非常令人沮丧，如果你能解决这个问题，我会非常感动。jQuery嵌套可排序 - 无法移动嵌套LI元素
我正在使用Interspire购物车，该购物车使用jQuery插件nestedsortables（http://code.google.com/p/nestedsortables/wiki/NestedSortableDocumentation）通过拖动和排列管理面板中的页面顺序掉落。下面是一个不同脚本的演示，它做同样的事情：http://mjsarfatti.com/sandbox/nestedSortable/
问题是父页面（在列表中，而不是实际页面）能够被拖入任何顺序，包括到嵌套的子位置并退出（直到刷新，然后卡在儿童位置）。子页面不能被拖动/移动，并且光标变成4路箭头，就像父页面一样。
我已经浏览了HTML很多次，我失去了计数。对于父母和孩子来说，HTML看起来几乎完全相同，我可以弄清楚为什么一个人会工作，而一个人不会。我想也许它与ul或li标签有关，但我只是没有看到问题。
我将我的代码与Interspire demo（http://shoppingcart.interspire-demo.com/demos）的代码进行了比较，我没有看到任何区别。他们的管理面板工作，我的不是。我尝试重新上传控制此功能的2个JavaScript文件，但问题仍然存在。
这里是一个HTML片段：

请帮助我。我相信其他Interspire和NestedSortable用户也会觉得这很有用。感谢您的关注，我非常感谢任何人试图解决这个问题，无论您是否成功。 };
我应该提供哪些其他信息来增加解决此问题的机会？ CSS，完整的HTML或工作演示中的HTML代码片段？我花了很多时间试图解决这个问题，并且真的可以使用第二双眼睛。 – Rob
