How to clone any element or block in DhtmlX JSON form

Hello All,

    I want to clone any block or item in dhtmlx form using JSON. I searched a lot but can't find any resource to implement it. 

I want the same functionality as it can be seen on link

jsfiddle.net/zUAQC/11/

Where we can easily Add/Delete/Copy input.

Any help would be highly appreciated.

Thanks,
Irfan
