 * Something in this plugin conflicts with my theme and prevents me from adding 
   new fields to a form. The edit form screen has these errors:
 * [Error] TypeError: undefined is not an object (evaluating ‘a.ui.sortable’)
    (
   anonymous function) (jquery.ui.nestedSortable.min.js, line 1) global code (jquery.
   ui.nestedSortable.min.js, line 1) [Error] TypeError: undefined is not a function(
   evaluating ‘h(“.vfb-cloned-options”).sortable({items:”div.option”})’) (anonymous
   function) (vfb-admin.min.js, line 1) j (jquery.min.js, line 2) fireWith (jquery.
   min.js, line 2) ready (jquery.min.js, line 2) J (jquery.min.js, line 2)
 * Any ideas on how to fix?
