How To: Restrict JQuery Droppable Areas To Draggable Type

You may view the code at:

I would like to know how to restrict the primary vignettes to the primary vignette droppable area and the secondary vignettes to the secondary vignette  droppable areas.

The Primary area is the larger area and the secondary areas are the smaller areas.

Is it possible to constrain what goes where?  If so, please explain how in a thorough manner.  While I certainly appreciate fixes, my real desire is to learn the how's and why's.  Thank you very much.

A simple solution in your case is to change the accept option for the two droppable areas. Change one from .imageAsset to .primary and the other from .imageAsset to .secondary. This will target the different pictures depending on what type they are and is self explanatory.
