I'm looking (fruitlessly so far) for a plugin, template, or loop modification that permits faceted browsing through posts. Essentially, this would be a way to recursively narrow a collection of posts by their categories, similar to the experience on HomeDepot.com.
For example, the navigation sequence could be...
- Category-1 > Category-2 > ... > Post
- Category-2 > Category-1 > ... > Post
...where each category available for filtering is based on the intersection of those chosen before. (Category-1 AND Category-2 AND ...)
I've looked around and the closest I've found is Scriblio, which I've found lacks clear documentation.
Any help or pointers would be appreciated.
