By far the single-most powerful, sophisticated and customisable filter stack available. Filter is a perfect choice if you've got a lot of items you want people to sort on a webpage. This stack works on the basis of assigning categories and keywords to items, which end users are shown and can use as a filter. On the surface, this provides a fast and easy method for people to sort your content. It also provides you, the RapidWeaver user, with a more simplified approach towards making items sortable. Filter is ideal to use in a wide variety of educational, e-commerce, business and creative projects.
