Question

I’m trying to add a parameter to a div once its dropped onto a droppable.
Is there a method which resembles addParameter below which can add the paramter ?

    $( ".placeHolder" ).droppable({ drop: function( event, ui ) 
            { 
       "#"+this.id.addParameter(myParam="testParam");
}

If you mean setting the attribute to the draggable element, then you can use:

$(".placeHolder").droppable({
    drop: function(event, ui) {
        ui.draggable.attr("myParam", "testParam");
    }
});

Otherwise, just use ui.draggable as a jQuery object of the draggable element.
