Slider drag n drop

Slider drag n drop


I am trying to implement the product slider example with drag and drop
functionality. I have a working example however, due to the overflow:
hidden; attribute on the slidergallery when you drag something from
the slider gallery it disappears when you move outside of the
slidergallery div. However, it works despite not seeing the draggable
item. Any ideas on how to circumvent this issue?
