Javascript tree menu not working in portal

Question

We are evaluating the possiblity of providing javascript tree menu in a portal page, which should work in both IE and Netscape browsers. The javasript tree menu ("COOLjsTree" at http://javascript.cooldev.com/) is working properly in all the browsers when accessed directly as a simple jsp file from the server. But when we create a java portlet of the same jsp file and try to access it from all the browsers, we are not able to see the menu in Netscape 4.75, while it is fuctioning properly in IE 5 and above and Netscape 6 and above.
We have gone through the note:136120.1 on Supported browser versions for oracle portal.
The question is why is the javascript not working when put as a portlet in portal on Netscape 4.75, whereas the same piece of code works properly on Netscape 4.75 when accessed as a simple jsp file?
We want to achieve this functionality and any help/clarification on this particular issue would be greatly appreciated.

I had a similar problem using a different Javascript menu. If you take a look at the HTML generated by the portal and break it down into smaller sections you may find the HTML that is causing your Javascript not to load. It's a tedious task, but not all Javascript is the same. Note, if your javascript is using or manipulating the <div> tag. It must be relative positioned to an image or div or you may run into the problem of the javscript loading and displaying relative to the browser as opposed to your portlets.
