Yesterday I have updated the Demo Site for mambo-phpShop. The template you can see there has been designed by mambosolutions.com. It's very nice and comes with a Flash Header and a JSCookMenu. The menu has been modified to show all Product Categories from your Shop.
The template will be the default template for the next release of the Mambo eCommerce Edition (which will be released shortly after mambo-phpShop 1.2 stable has been released). Just have a look over there, place an order and explore the features of the recent CVS Snapshot version.
