Drag and drop

Drag and drop

Hi,

looking for some help here, I have to create functionality that does the following and am looking for some pointers as to how to go about it.

on screen there will be two container divs, the one on the left will be empty and the one on the right will contain a selection of thumbs,

I want to be able to drag these thumbs from the right hand box and drop them in the left hand box, on drop they will snap to a grid, it will also then disappear from the right hand box,

Once any more than one has been added to the box on the left I want to then be able to drag these about which will wffectively be used to order them.

Any help would be much appreciated as not sure where to start!

Cheers

Segles
