If you are interested, I used a workaround for dragging a cell. The item to
be dragged is the cell's contents, and the drag handle is the cell itself.
Now, the standard idrag.js looks for an optional handle going down the
hierarchy. I made this change:
var dhe = o.handle ? (o.handleUp ? jQuery(jQuery(this).parents(o.handle)[0])
: jQuery(this).find(o.handle)) : jQuery(this);
on line 503 of the idrag.js file.
So calling a drag
$('a.classname').Draggable({ handleUp:true, handle:'td' });
Would move the A element around, but the handle initiating the drag would be
the TD.

I think you're going to have issues trying to drag a <td /> cell around. It
could cause unexpected results.
To answer your direct question though, this should grab the value of the
hidden form field:
$("input:hidden", $(drag)).val();
Or you could use:
$(drag).find("input:hidden").val();
And dozen more. I'm not sure which of the two is this most "efficient"
method, but I tend to use the first option.
