Description
Facet Stack add-on adds a new type of facet to FacetWP that groups values from multiple existing filters into a single consolidated list.

Key Features
- New facet type
Registers an additional type in the list of available facets within the FacetWP panel. - Multiple source grouping
Combines values from different configured facets into a single unified structure. - Compatibility with existing facets
Utilizes facets already created on the site without requiring reconfiguration of the original sources. - Configuration via default panel
All stack setup occurs within FacetWP’s own administrative interface. - Consolidated filtering for visitors
The end user interacts with a single filter box covering multiple data categories.
Benefits of Facet Stack
