我正在开发一个项目，现在包含一个包含可拖动div的可打开菜单。我已经设置了一个带有droppable的网格，所以当我从菜单中拖动div并将其放在网格上的一个div上时，div我将它放在克隆上。
您可以将此想象为抓取桌面上的图标，然后将其放在其他位置。
我遇到的问题是，当我第一次放弃div时，看起来很正常，如下所示：http://i.imgur.com/nnSGFaF.png
但是当我抓住被丢弃的div并将其拖到另一个框中时，会发生一些非常奇怪的事情，就像这样（我在该列中不断抓住并从顶部到底部删除了div）：{{3} }
原谅我，我尝试设置一个jsfiddle，但它不太有效。单击左侧的栏时，带有可拖动div的菜单无法打开。请随时尝试使其工作！ jsfiddle.net/MarcosPortugal/KWJzS /

javascript代码（最后一部分，在“jQuery for the website”评论之后，对于这个问题最重要）：

请帮助我，因为我一直试图解决这个问题几个小时，但找不到解决方案。如果事情不明确，请问我，我会解释！非常感谢你！
