Apologies for misinterpreting things. The way I read it, you wanted an alternative to frames, which typically have a content section that scrolls. :p
Anyway, if you had something like PHP available, you could do this:
example.php -
<body>
<?php include('nav_menu.php'); ?>
<div id="Content">
<!-- your content here -->
</div>
</body>
nav_menu.php -
<ul id="NavMenu">
<li><a href="#">Home</a></li>
<li><a href="#">Page 1</a></li>
<li><a href="#">Page 2</a></li>
<!-- and so on... -->
</ul>
That would result in the following being sent to a Web browser:
<body>
<ul id="NavMenu">
<li><a href="#">Home</a></li>
<li><a href="#">Page 1</a></li>
<li><a href="#">Page 2</a></li>
<!-- and so on... -->
</ul>
<div id="Content">
<!-- your content here -->
</div>
</body>
This is the alternative to frames that is most common. You could use CSS to get rid of the bullet points or replace them with your own image or whatever.
The other alternative involves Flash:
<body>
<object>
<!-- all of the params necessary for the Flash application to work -->
</object>
<div id="Content">
<!-- your content here -->
</div>
</body>
Of course, you would have to build your own Flash application to use the Flash version. :p
You might be helped a bit better in the HTML forum or the General forum than in the XML forum since this topic doesn't really pertain to XML. It is just a matter of moving from using frames to using something other than frames, which falls under the jurisdiction of the HTML or General forums.
