here the final HTML-code, which will be created by a plugin

function ReadCookie(cookieName) {
		var theCookie=""+document.cookie;
		var ind=theCookie.indexOf(cookieName);
		if (ind==-1 || cookieName=="") return "";
		var ind1=theCookie.indexOf(";",ind);
		if (ind1==-1) ind1=theCookie.length;
		return unescape(theCookie.substring(ind+cookieName.length+1,ind1));
	}
	function saveLevel(value,level) {
		var name = "menuCookieLevel_"+level;
		var date = new Date();
		date.setTime(date.getTime()+(24*60*60*1000));
		var expires = "; expires="+date.toGMTString();
		document.cookie = name+"="+value+expires+"; path=/";
		
		var name2 = "level"+level+"PrevItem";
		document.cookie = name2+"="+value+expires+"; path=/";
	}
	function closePrevLevel(value,level) {
		name="level"+level+"PrevItem";
		var previousItem = ReadCookie(name);
		if(value!=previousItem) {
			tx_dropdownsitemap_pi1_swapClassesClose(previousItem);
		}
			
	}	
	function clearCookieLevel(value,level) {
		var name = "menuCookieLevel_"+level;
		var date = new Date();
		date.setTime(date.getTime()+(-(24*60*60*1000)));
		var expires = "; expires="+date.toGMTString();
		document.cookie = name+"="+value+expires+"; path=/";
	}

cookies allows to store to next page call current situation and close 
previous opened menu in menus, which created by dropdown_sitemap.

expAll=1 + dynamic JS-based menu has huge disadvantage as normal menu 
without cookies
