The site contains over 100 pages generated by over 10 .XAR files and periodically more will be added. At the moment the Home page has a top level Navbar in the first .XAR and the other .xars each have their own Navbar.
I have prepared a single Navbar which covers all pages. Now I want to just insert the same navbar into all pages, say, via a placeholder. However my HTML coding is almost non-existant.

I have tried using an iFrame in a placeholder but although I can get the menu page to display in the placeholder there appear to be two problems

<iframe src="http://<domain_name>/menu/menu.htm" width="955" height="90"></iframe>

1. Scroll bars are displayed even tho I tried scrollbars="no" meaning that the navbar has to be scrolled. Increasing the height of the placeholder does not seem to make any difference
2. The submenus drop down within the placeholder and are not visible over the main page.

Two questions please
Is this the way to accomplish it
Where can I find a reference please (I am working my way thru WWW Schools)
