3 Levels Javascript Tree Menu

[devil_vin]

HI,guys! I would like to create a 3 level javascript tree menu.
Here are the first level menu items.

var myTree = new Tree ("myFolder");
myTree.addTreeItem("f1");
myTree.addTreeItem("f2");
myTree.addTreeItem("f3");
myTree.addTreeItem("f4");
myTree.addTreeItem("f5");
myTree.addTreeItem("f6");
myTree.addTreeItem("f7");

How can I use addTreeItem() to add menu items up to 3rd level from each
1st level items?
I need to corporate with some icons as well if item is clicked,for example the hierachical line and +/- are displayed which similiar with xml menu.

Thanks...

Hey devil_vin,
The object Tree is not inbuilt object of Java script so not sure what are the capabilities does it have.
try this

var myTree = new Tree ("myFolder");
myTree.addTreeItem("f1");
var myTreeNew = new Tree ("Test");
myTreeNew.addTreeItem("Link1");
myTree.addTreeItem(myTreeNew);

Mostly this will fails as i am not sure if the Tree object supports this kind of object addition. But its always better to try and fail rather than not trying and failing
