I am currently using Dreamweaver CS4 to make an intranet mockup.
Looking for a kind of include (namely, for a menu shared by all pages) without server-side scripting, I found that Dreamweaver propose a handy library.
a) You open window -> assets
b) from the asset panel, you create a new library item.
It creates a ‘.lbi’ file.
c) then, you can place this item anywhere in your pages. When you update your .lbi library item, DW propose you to update automatically all files in which it is included.
