/**
|
|
* HTML_TreeMenu Class
|
|
*
|
|
* A simple couple of PHP classes and some not so simple
|
|
* Jabbascript which produces a tree menu. In IE this menu
|
|
* is dynamic, with branches being collapsable. In IE5+ the
|
|
* status of the collapsed/open branches persists across page
|
|
* refreshes.In any other browser the tree is static. Code is
|
|
* based on work of Harald Radi.
|
|
*
|
|
* Usage.
|
|
*
|
|
* After installing the package, copy the example php script to
|
|
* your servers document root. Also place the TreeMenu.js and the
|
|
* images folder in the same place. Running the script should
|
|
* then produce the tree.
|
|
*
|
|
* Thanks go to Chip Chapin (http://www.chipchapin.com) for many
|
|
* excellent ideas and improvements.
