FacetWP is an advanced filtering and search plugin that allows you to create faceted search and filter options. The plugin is written by Matt Gibbs and is down right stellar. I gave it a quick run for this review and was very pleased with what I found.
In Matt’s own words:
Facets are interactive elements for filtering lists of content.
You’ve seen facets on sites like Amazon and eBay. Use FacetWP to improve eCommerce sites, staff directories, resource libraries, search pages and a whole lot more!
To get a real idea of just how powerful FacetWP is, take a look at Matt’s live demo.
You can see a live example of how I and some co-developers implemented FacetWP very effectively on CGCookie.com.
