| This page has a double drop-down menu at the
head. It can be very useful for sites with many pages and can quite neatly replace several
single drop-down menus.
You can select a subject in the left-hand menu and then choose a
page-to-go in the right hand menu. Of course, the right-hand menu updates according to the
subject you have chosen.
The menu has only two or three files to go, so the working of the menu
isn't complicated by a great deal of detail. The triple menu for has lots and lots
of files, so its code appears to complex, when really it is quite simple.
Go for the code.

There is also using different code.Like much of the stuff in
JavaScript, the long bit is filling in all the file details. The code is actually quite
simple.
