How do you arrange site after tag?
See attachment
I gues is impossibile 
Best regards
You're going to need some custom development work done to integrate categories and tags because the two are not related.
Why not use Product Features and Product Filters as you will be able to achieve something this without any custom development which may require re-working every time you upgrade CS-Cart.
StellarBytes i gues is imposibil to make this ahrdest work:)
