72 <p>Provide feedback to users as they drag an object in the form of a helper. The <code>helper</code> option accepts the values 'original' (the draggable object moves with the cursor), 'clone' (a duplicate of the draggable moves with the cursor), or a function that returns a DOM element (that element is shown near the cursor during drag). Control the helper's transparency with the <code>opacity</code> option.</p>
73 <p>To clarify which draggable is in play, bring the draggable in motion to front. Use the <code>zIndex</code> option to set a higher z-index for the helper, if in play, or use the <code>stack</code> option to ensure that the last item dragged will appear on top of others in the same group on drag stop.</p>
