Hi Diez
yes, it works now. thanks for your help!
Below are the code snippets just in case someone runs into the same problem:
from the controller (root.py):
====================
from tg import tmpl_context as c
from tw.jquery import TreeView
@expose('helloworld.templates.about')
def about(self, **kw):
myTree = TreeView(treeDiv='navTree')
c.tree = myTree
mytext =""" <ul>
<li class="open"> product12
<ul>
<li>item1</li>
<li>item2</li>
</ul>
</li>
<li class="open"> product34
<ul>
<li>item3</li>
<li>item4</li>
</ul>
</li>
</ul>"""
return dict(mytext=mytext)
template (about.html):
===============
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

</head>
<body>
${tmpl_context.tree()}
<div id="navTree">
<div py:strip="True" py:content="XML(mytext)">
</div>
</div>
</body>
</html>
