[Pekkonen]

Hello,
I need create in main voices of my menu subitems with links to products pages.
Category1
- Product1-from-category1
- Product2-from-category1
- Product3-from-category1
...
and accordantly products from category2 and category3.
Product1-from-category1 it's will be subitem of main menu (<ul><li><a href="link to Product1-from-category1"></a><li></ul>)
Will be great when with new Product will be add to VM - automatically will be created new subitem to this product ( ProductN-from-category1)

PS VM 2.0, Joomla 1.7.3
