/** |
40 |
* HTML_TreeMenu Class |
41 |
* |
42 |
* A simple couple of PHP classes and some not so simple |
43 |
* Jabbascript which produces a tree menu. In IE this menu |
44 |
* is dynamic, with branches being collapsable. In IE5+ the |
45 |
* status of the collapsed/open branches persists across page |
46 |
* refreshes.In any other browser the tree is static. Code is |
47 |
* based on work of Harald Radi. |
48 |
* |
49 |
* Usage. |
50 |
* |
51 |
* After installing the package, copy the example php script to |
52 |
* your servers document root. Also place the TreeMenu.js and the |
53 |
* images folder in the same place. Running the script should |
54 |
* then produce the tree. |
55 |
* |
56 |
* Thanks go to Chip Chapin (http://www.chipchapin.com) for many |
57 |
* excellent ideas and improvements. |
