Let's say that I want to create a very basic website that has five pages or so. All pages have the same header, footer and navigation. Obviously, it's very inefficient to create these in all pages page by page. Does DreamWeaver have a feature to create a ... template? What I want to do is to create common components like header, footer and navigation just once. Also if and when I modify them, I want all other pages to be updated automatically. Can this be done using DreamWeaver?

If you were going to use the Same everything except for the main content box just use an iFrame, its easy to make.
