braducrumb only on product detail page

www.francavillaturismo.it

I've a menu with product categories.If i assign breadcrumb to menu categories i see the module in all products detail page but also on every category page.
I want breadcrumb only on products detail page....

Sorry for my english....

You must have menu items (at least in hidden menus) associated with pages in order to control module apperiance

This means that every time i add a product, i have to create an associated (hidden) menu entry also!?

The people that will insert products dont know how to create menu entry...

yes, you need to organize things in such way so you overcome this joomla limitation.
