Pivot Table - move fields on IPad (touch events)

Hi all,
I am trying to go through the Pivot Table features. I cannot find any details on how to support Drag and Drop on Pivot Table fields from IPad or any touch based device. Can someone please guide me regarding this issue?

In other words, how can I add or remove fields in Columns/Rows/Data from IPad?

Thank you,

AK

Unfortunately currently it is not available to drag-n-drop dhtmlxPivot fields on touch devices.
