Javascript-форум - обращение к cookie из JavaScript

есть меню на JavaScript + CSS
скрипт заносит информацию в куки и при обновлении страницы (F5) меню отображается такое какое было на момент перезагрузки, а нужно что бы при обновлении страницы меню было свернуто.
как это сделать подскажите, пожалуйста!
