Answer 1

Instead of $('#cssmenu li').removeClass('active'); , use $(this).closest('#cssmenu').find('li').removeClass('active');

Similarly instead of $('#cssmenu ul ul:visible').slideUp('normal'); , use $(this).closest('#cssmenu').find('ul ul:visible').slideUp('normal');

By using it like this one accordion menu will not interfere with the other one

(function ($) {
    $(document).ready(function () {
        $('#cssmenu ul ul li:odd').addClass('odd');
        $('#cssmenu ul ul li:even').addClass('even');
        $('#cssmenu > ul > li > a').click(function () {
            $(this).closest('#cssmenu').find('li').removeClass('active');
            $(this).closest('li').addClass('active');
            var checkElement = $(this).next();
            if ((checkElement.is('ul')) && (checkElement.is(':visible'))) {
                $(this).closest('li').removeClass('active');
                checkElement.slideUp('normal');
            }
            if ((checkElement.is('ul')) && (!checkElement.is(':visible'))) {
                $(this).closest('#cssmenu').find('ul ul:visible').slideUp('normal');
                checkElement.slideDown('normal');
            }
            if ($(this).closest('li').find('ul').children().length == 0) {
                return true;
            } else {
                return false;
