Multiple Variable Drag and Drop demonstration

Nandish,

For what it's worth, I'm not sure what you want to accomplish by adding JS. What you have now is working, and seems to me to have all the functionality you want. Adding JS seems unlikely to add much to it, but will make it harder to maintain, and harder for you to modify. Two thoughts: Steve is probably using JS to carry dropped locations to other slides, whereas it seems your interactions are complete if you can get amphibians placed under cold blooded. Steve can work up something with JS in it, but if you can't create it on your own, how will you modify it? What I'm saying is that you will need to learn enough JS to create it yourself, if you want to be able to change it, if needed.

I say, "It's working and looking good. That's the goal. Time to move on."

Just my opinion.
