Will JS work?

I’m trying to avoid using frames, even though I think they would work in this situation, but was wondering if JS would work…

My problem right now is that anytime I want to change or add an item to my left side menu, I have to change every page on my site to reflect this. What I would like to have happen is that I put the menu in an external file, change it once & the change is reflected on every page.
The [URL=”http://www.dynamicdrive.com/dynamicindex1/davidmenu.htm”]sliding javascript menu[/URL] does this….I change ssmItems, which is an external file, and the changes are on every page. BUT, I don’t want to use the sliding concept in this instance. I just want the menu to be a part of the page.

Is this possible?

Is javascript the way to go even? I thought CSS might do it, but now I think no.

Does this even make sense? Any suggestions?

Also in #JavaScript _↴
