The
menu on the left is an example of a vertical column Sliding type.
This operates when the user clicks on a particular subject, the other
items then slide down, revealing a previously hidden choice of
submenus to choose from.
Appearances
such as speed, colour, fonts, image background, icons, sounds and
text alignment, can be fully customized to fit in with your website.
As this menu is for illustration purposes only, the links in this
example have been removed.
