When cloning a select, and one of the options has been selected, the selected option isn't selected when cloned.

Try making a select with 2+ options and select the second option, and then clone the select. In the new cloned select, the selected option is now the first (the select has been initialized).

Here is a fixed clone() function that remembers the selected option:

jQuery.fn.clone = function () {
    var result = original.apply(this, arguments),
        my_textareas = this.find('textarea').add(this.filter('textarea')),
        result_textareas = result.find('textarea').add(result.filter('textarea')),
        my_selects = this.find('select').add(this.filter('select')),
        result_selects = result.find('select').add(result.filter('select'));

    for (var i = 0, l = my_textareas.length; i < l; ++i) $(result_textareas[i]).val($(my_textareas[i]).val());
    for (var i = 0, l = my_selects.length; i < l; ++i) result_selects[i].selectedIndex = my_selects[i].selectedIndex;

    return result;
};
})(jQuery.fn.clone);
