 * Instructions: Call $(selector).relCopy(options) on an element with a jQuery type selector 
 * defined in the attribute "rel" tag. This defines the DOM element to copy.
 * @example: $('a.copy').relCopy({limit: 5}); // <a href="example.com" class="copy" rel=".phone">Copy Phone</a>
 *
 * @param: string   excludeSelector - A jQuery selector used to exclude an element and its children
 * @param: integer  limit - The number of allowed copies. Default: 0 is unlimited
 * @param: string   append - HTML to attach at the end of each copy. Default: remove link
 * @param: string   copyClass - A class to attach to each copy
 * @param: boolean  clearInputs - Option to clear each copies text input fields or textarea
 *

            }); // end click action
        }); //end each loop
        return this; // return to jQuery
    };
})(jQuery);

select2 intiation code is

$(document).ready(function() {
            $(".select2").select2({
                width: "100%" /*,minimumInputLength: 3*/ ,
                maximumInputLength: 3000000,
                maximumSelectionLength: 30,
                tokenSeparators: [",", " "]
            });
        }
