Demo & complete code is like this : https://jsfiddle.net/oscar11/vs4zggjf/

I want to make to be like this : http://imgur.com/wIFwON3. So,I would like to add some conditions. Customers can only drag in room type. While room type can not drag to the customer. whether it can be done? I have tried but did not succeed.

I take from here : https://johnny.github.io/jquery-sortable/#connected

Thank you
