Hey guys I have a page where a user can drag and drop ellements into divs 's and everything works great, but I need the div to only accept 1 element.

Check it out Click Here
Right now you can drag both pdf docs into one "send to print" div. I need to able to either kick out the existing one or not allow the second ellement to be dropped at all.

Any ideas??

Sorry for the link this is the correct link Click HereIm looking at the page that you suggested above and Im not sure if that is what I need, I will look over it good, but I need to make sure that the user cant stack 2 in the same div.

Ale, do you think you could show me an example of how this would work? I know its aggravating for newbies like me to bother you like this.

Is not too much pretty, but it works:

                    if ( ui.item.parent().children().length > 1 ) { // check if it has more than one item
                        alert("You can drop only one item in here!"); // alert something
                        $("#sortable1").append( ui.item.detach() ); // detach the dropped item from the dropped target and append it to the previous container
                    }
                }
            }
        }).disableSelection();
    });

<ul id="sortable2" class="connectedSortable acceptOnlyOne" style="min-height: 30px; min-width: 100px; border: 1px solid black;">
</ul>
