@rajeeshvr Are you associating the Taxonomy with the Post Type? Many of the folks who have jumped on our Slack are creating ‘relationships’ to the Custom Taxonomies they’re creating, but they’re not associating those Taxonomies with the Custom Post Type. Those two are not interchangeable.
In addition, you have to have an Archive enabled for your Custom Post Type in order to get any taxonomy work to display properly in Search & Filter.
We’d only be able to help you with your shortcode question if you provided us details about your configuration. From your shortcode, I’m guessing you have a post-type ‘resource’ and a taxonomy ‘county’. Verify spelling and verify those two are associated in Pods (Advanced Options, very bottom of the screen, ‘Associated Post Types’ on the Taxonomy Advanced Options, ‘Associated Taxonomies’ on the Post Type Advanced Options.
