To create pages that enable dynamic navigation, you use two servlet beans, atg.commerce.search.refinement.CommerceFacetTrailDroplet and atg.repository.search.refinement.FacetSearchDroplet. You use these servlet beans together to render facets and facet trails on pages, and, based on the selection ranges or values chosen by customers, to issue queries to ATG Search. You can then use other servlet beans to render the results returned by the queries.
