JavaScript Multi-level Navigation Menu with States-Remember © JavaScriptBank.comThis JavaScript code example will create a multi-level navigation menu on your web pages (in the live demo of this JavaScript code example, we have 3 levels; and obviously you can add as many levels as you want).The advantages of this JavaScript code example are in following good ideas: just one root of menus opened at the same time; besides, this JavaScript menu navigation script uses cookie to store the states of menus, they will keep the old states every time the web pages will be refreshed.
