选择的插件选项不会传递给克隆行

SETUP我正在使用Chosen插件（ http://harvesthq.github.com/chosen/ ）和使用relCopy脚本进行克隆

问题我可以成功克隆行，但“max_selected_options”之类的选项不会传递给克隆行。 请告诉我我做错了什么？

我认为事件不会分配给新克隆的元素，即使在克隆方法中指定了“true”属性。

无论如何，这是一个快速的解决办法，以确保事件始终附加。

CSS

 .hidden { display:none; /* to hide template */ } 

这不是完美但会让你朝着正确的方向:)

希望有所帮助。
