The only thing that comes to my mind are Library items, used in Dreamweaver MX.
Library items are fragments of HTML; that is, they are not a complete HTML document. They are a sequence of HTML that you can reuse in many documents on your site. Any information that appears on many pages in a site and may change from time to time is a candidate for library items, including the following:
• Navigation systems
• Contact information
• Telephone/pager/fax numbers
• E-mail addresses
• Street addresses
• Logos
• Copyright notices
I used Library items on my last web site, which had 100+ pages. I used them for the top and side nav menus, copyright info, and for various content blocks that would change from time to time.
Dreamweaver Library Items function on the same principle as Dreamweaver Templates, but they are used for sections of pages as opposed to entire pages. A master Library Item is created and then can be added to any number of pages. When an update is needed, the Library Item itself is updated and then changes are propagated to all instances of the Library Item throughout the site.
