Hi,

I am trying to do a TreeMenu in jsp.
Can anyone help me/give me a clue to write ExpandALLNodes() and CollapseALLNodes() functions in javascript in a TreeMenu.Such that all the treemenu nodes(parent/child nodes) should collapse/expand when a button is clicked.

Thank you,
Hadley

@MrNobodyJan 30.2009 — The general outline is:
[CODE]var parent = document.getElementById(id);
var children = parent.getElementsByTagName(tag);
var x, child, len = children.length;
for (x=0; x<len; ++x)
{
child = children[x];
// do what needs to be done to child
}[/CODE]

@MrNobodyFeb 01.2009 — What I posted is the basis for such a function. I'm not going to simply write all the code for you. Make some effort of your own. If you run into troubles, post back and I'll help out.
