I have the following:

I am trying to set it up so that when you drag the item, it only gets dropped to the div element which you can see, and is not covered up.

So I used this js:

$(".draggable").draggable({
    helper: "clone"
})
$("#bottom, .draggable").droppable({
    drop: function(event, ui) {
        var $this = $(this),
            $dragged = $(ui.draggable);
        $this.append($dragged.clone());
    },
    hoverClass: "dragHover"
})​

But it drops the element in both places even though only one of the drop zones is not visible!

How do I fix it so that this does not happen?

    Try setting with accept function.
    The working demo.

    $("#bottom, .draggable").droppable({
    drop: function(event, ui) {
        var $this = $(this),
            $dragged = $(ui.draggable);
        $this.append($dragged.clone());
    },
    accept: function () {
        var $this = $(this), divTop= $("#top");
        if ($this.is(".draggable")) {
          return $this.offset().top < divTop.offset().top + divTop.height() ;
        }
        return true;
    },
    hoverClass: "dragHover"
})​;​
