When a product exists in multiple shops, you can set a description specific to each shop, or the same for multiple shops.
This is where Sc Store Tree comes into action.
The description you'll be writing on a product will be applied to shops selected in the store tree.
In this first example, the description will be applied on Shop 1 only.
In this second example, for the same product, the description you'll be writing will be applied on Shop 2 only.
In this third example, the description you'll be writing will be applied on both Shop 1 and Shop 2.
Sc Store Tree has a very important role when working in multistore mode. It allows you to set the various product properties in all your different shops, as you wish in a very easy and simple manner.
