This menu technique is for cases where you have a number of pages on your site.
BS Editor: This menu technique is ideal for cases where you have a number of pages on your site, and may need to frequently change the menu items on all or many of them. Using an iframe within a floating Layer, the menu items are contained in a single external html page. You insert the layer code once into each page -- and when you must change the menu, you change a single external page. with the changes instantly reflected in every page on your site.
There are other ways to do this, of course. You can use server-side Perl or PHP scripts with an include to bring the menu content into your page. But this requires knowledge of scripting that some webmasters may not possess; and, of course, if your server (such as many freeservers) does not offer server-side scripting capability, that more complex server-scripted approach is unavailable to you.

The menu-in-iframe-in-layer approach, however, offers a clean, simple-to-manage alternative that anyone can use with nothing more than basic html skills. you can free download Layer Menu Uses External Page now.
