НАСТРОЙКА Я использую подключаемый модуль Chosen (http://harvesthq.github.com/chosen/) и клонирование с помощью скрипта relCopy
ПРОБЛЕМА Я могу успешно клонировать строки, но такие параметры, как "max_selected_options", не передаются в клонированные строки. Посоветуйте, что я делаю не так?

*
* 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
*
