Drag and drop on the iphone/ipod

Drag and drop on the iphone/ipod

Hello,

I have a drag and drop feature that works fine on the computer browsers.

It can be seen at http://www.thalasoft.com/elearning/exercise/55/page/201/subscription/

But on the iphone/ipod it's a different story.

The dragging is apparently disabled for it is already a feature of the device.

What solution can be used to solve this issue and have a drag and drop on the iphone/ipod ?

Thanks for any tips.
