efficient updating?

[jp_5282]

I'm working on a website that has a set of navigation menus written into every upage. Unfortunately, this design means that if I want to change the look of the menus, add a button, etc then I must manually go through *each and every* page on the site updating the code appropriately. Is there a more economic way to set up these navigation menus on my site such that I can make changes to a single place and all pages reflect that change?

thanx,
Jeremy

yes, use a server side include.
<!-- #Include virtual="themenu.html" -->
something like that. Figure out of your server supports server side includes, and if they support and server side languages. If it turns out that includes are not an option and your server supports no server side languages, then there is always the iframe.
