helper: "clone" compatibility

[mafar]

When used with options like
appendTo: document.body, helper: "clone",

Does not behave correctly.
Check Fiddle: http://jsfiddle.net/bababalcksheep/Zr85J/4

helper: Cole is important to fix z-index issues of dragged elements. Kindly tell me how to fix it .

I fixed it via http://jsfiddle.net/bababalcksheep/Zr85J/5/.
Kindly provide built in support to turn on clone internally. as this still needs workaround for exampel placeholder size etc .. placeholder offset for 'child'

        stop: function (e, ui) {

            var elements = ui.item.data('multidrag');
            ui.item.after(elements).remove();                    
        },
          helper: function (e, item) {
              if (!item.hasClass('ui-state-focus')) {
                  item.addClass('ui-state-focus').siblings().removeClass('ui-state-focus');
              }
              var elements = item.parent().children('.ui-state-focus').clone();
              item.data('multidrag', elements).siblings('.ui-state-focus').remove();
              var helper = $('<li/>').css('list-style', 'none');
              helper.height('auto');
              return helper.append(elements);
          },
