How to make a Drag and Drop

Hi, I'm new to this Adobe Edge and tried to do a Drag & Drop, the examples I've seen have not worked.

I wonder if someone could share a file with  Drag & Drop with validation.

What I need to do and would like to learn is:

I have 4 buttons that I can drag and a box that I drag the right choice. If the option is correct stays, it is if it was incorrect is returned to its place of origin.

I hope I can help, I will be very grateful.

Thank you very much friends
