I have found and tried by myself a super workaround on this page.
Just copy classes from his example and add the custom itemRenderer to your source list.
<s:List id="srclist"
allowMultipleSelection="true"
dragEnabled="true"
dragMoveEnabled="true">
<s:itemRenderer>
<fx:Component>
<local:DraggableIconItemRenderer decorator="{DragThumb}" />
</fx:Component>
</s:itemRenderer>
</s:List>
