I'm a newbie to Magento.
I've 2 root categories and sub-categories as follow.
Root Catalog Site1 - Sub-category 1.1 - Sub-category 1.2 - Sub-category 1.3 - Featured Root Catalog Site 2 - Sub-category 2.1 - Sub-category 2.2 - Sub-category 2.3
I created 2 sites as mainstore.example.com and store2.example.com I created some products for each of categories. When I create some products of Sub-category 2.1, 2.2 and 2.3, I'll marke as featured products at Featured category of Root Catalog Site1.
And I want to display same Featured products at every stores of the example.com.
How can I link between two categories in different root catalog?
