Magento

Hello.
I have to create separate websites for each main category from the initial website.... and still have all the categories on the main site…

for example, I have a category ‘Pizza’. I have to create a new website whose root category is Pizza. The only way I managed to do this is making a new category named Pizza in the root catalog and MOVE the contents of the category pizza into it. created the store, assigned the root category pizza, works ok.......but in the main website i don’t have any pizzas…

Do you have any idea how could I make this work?

Thanks.
