Core Features of FacetWP WordPress Plugin
- Smart Filtering: helps users find what they’re looking for faster by showing only relevant filtering choices, leading to happier customers and increased sales
- Use of existing data: filters are created using your site’s existing custom fields, taxonomies, and post data (author, post date, post type, etc.)
- Lightning Fast: ajax-based filtering happens quickly and without page refreshes, with an index table for extra speed
- Compatibility with most themes: facets can be added anywhere on your page using shortcodes or PHP, with built-in features like pagination, sorting, and user selections also available through shortcodes
- Wide range of facet types: includes checkboxes, dropdowns, date ranges, sliders, and proximity (geolocation) filters
- Developer friendly: developers can customize the plugin using its many hooks for a high degree of customization.
