HierarchicalCatalogPartialRouter includes the name of the catalog in the route, so I'd say this functionality is there out of the box. Example:

/catalog1/categoryA

/catalog2/categoryB

Hi Juan,

Please try the below code hope it will work in your case.

The HierarchicalCatalogPartialRouter class constructor takes two parameters one is the route starting point and another commerce root (catalog root). In commerce root, we can try to pass the second catalog root and then check it's work or not.

• Root/category1
• Root/category2

CatalogContent secondCatalog = contentLoader.GetChildren<CatalogContent>(rootLink).Skip(1).FirstOrDefault();

Func<ContentReference> startLink = () =>
ContentReference.IsNullOrEmpty(SiteDefinition.Current.StartPage)
? SiteDefinition.Current.RootPage
: SiteDefinition.Current.StartPage;

RouteTable.Routes.RegisterPartialRouter(new HierarchicalCatalogPartialRouter(startLink, secondCatalog, false));
