modifying static content for all pages?

[mr_newbie]

supposing you have a dozen HTML pages, with the same navigation menu. then one day you need to add another link to the menu.
Does that mean you have to modify the menu code in each HTML file individually?

Isnt there a way to load the menu html externally? so that you only have to modify the menu.html
