This page is the starting point of the Manipulator Stack demos. It does not contain any Menupilator Stacks, so this is how the menu looks like out of the box.
On the other pages, a lot of Manipulator Stacks are used to change individual menu items on those pages.
For this demo site, the Elite theme
(designed by Henk Vrieselaar, now sold by ThemeFlood) is used.
