I want to create an facet for ProductType field, and then for each value, a sub-facet of product groups. This is quite common to do in ElasticSearch using aggregations, but I can't quite wrap my head around doing so with DW Facets. "FacetOptions" loop items don't seem to have a Facet loop available under them, which makes me think it's not possible?
So to put it in another way, I would like to retrieve
- ProductType Facet
- For each value, create a sub-facet of available product groups for those ProductTypes.
