ApPHP Multilevel TreeMenu Control

The ApPHP TreeMenu is a PHP script that generates multilevel tree menu control. It was specially designed for web developers. Tree menu is one of the most popular and commonly used navigation controls and it allows you to set up and use in no time. It has a collapsible vertical tree listing, that resembles the Windows Explorer folder view. It also makes it easier for visitors of your website to find things, makes its look more professional and helps to organize large amount of data into hierarchical order with as many nodes and sub-levels as you need. Expandable elements can be used as links, or they can be just expanded. The sub-menus are opened and closed by a mouse click. The code is object-oriented with two classes: the TreeMenu class creates the tree structure and the Node class is used for each menu item. Simple CSS defines the look of the tree and can be changed with ease.
