So, I've got a lot of CPTs (Custom Post Types) and Taxonomies. Creating them isn't too hard, displaying theme is too bad either. Adding back-end filters are not an issue for me either.
However, I'm at a loss how to offer a client friendly way to build / modify front filters that dynamically affect how my CPT data is shown on any given (non-logged in) visitor facing page.
An example would be WooCommerce's Products (which is a non-hierarchical custom post type). The included layered navigation widget simply is too limited as is the ajax counterpart sold separately as an extension IMO.
So far, the only thing that's potentially that I've found that's capable enough is this: http://wp-types.com/ - though it's expensive / complicated but powerful.
Surely, this can't be the only plugin solution (commercial or not) for building Front-End filters, is it? If you're aware of something that makes building functioning interfaces for end-user / visitor filters simple, I'd like to hear about it.
If there's simply nothing out there, then that's seems like a ripe opportunity for some CodeCanyon author to make a tidy sum potentially.
Thanks in advance to anyone who responds.
