Expanding_Tree_Menu_Asp_Code

国外网站找到的一个树形菜单，可以后台添加编辑条目。感觉还不错。下面的它的介绍escription: Displays a Tree Menu navigation system on your website. The 'folders' and 'sub-folders' information is stored in a database. The tree menu is diplayed and clicks made in the menu are all actioned with JavaScript (client-side), so your visitor does not need to wait for the menu to retrieve info from the server everytime the click on an item. Also, a link to a new page is clicked, the menu will open on the new page to show the link that was clicked.
