Draggable story book

Draggable story book

I need to create a customizable story book.
In the middle of the page I have a DIV that represents the book page.
On the right side I have some characters, accessories and so on.
I want to drag'n'drop the elements into the book page and then get the coordinates of each object dropped into this div since then I want to save these coordinates for printing the book.
I also want if the user drag'n'drop the character outside the div move it to the original place.
Do you know of something similar to what I am looking for? Maybe a similar situation or solution?

Thanks in advance to all the community!
