Hi, I have a div tag as a â??containerâ? for all my draggable objectsâ?¦ My  
goal is to be able to decide whether to revert these objects based on  
where they are dropped. If they are â??out of boundsâ?, or not in the  
container after theyâ??ve been dropped, I want them to revert, otherwise,  
drop normally.

I currently have a few JS functions setup that calculate the boundries  
of the container, and alert me on mouseupâ?¦ true if theyâ??ve been dropped  
outside of the container, and false if theyâ??ve been dropped inside the  
container.

By default, the droppable object is not set to revertâ?¦ How would I go  
about making this object revert only if itâ??s been dropped outside of the  
container?

Thanks ahead of time for any helpâ?¦

Please, this is definitely not a question for a Ruby mailing list.

You would do better asking this on a JavaScript or DHTML mailing list.
