Tags in Location

Hi,

you can try to add this in your theme functions.php

function em_location_tags(){
 register_taxonomy_for_object_type(EM_TAXONOMY_TAG, EM_POST_TYPE_LOCATION);
}
add_action('init','em_location_tags');

then the next step is to add a custom search attributes – https://wp-events-plugin.com/tutorials/creating-custom-event-search-attributes/ (replacing events with locations)

e.g. something like this – https://pastebin.com/UMipT093

Try one of these plugins

custom post types ui
pods framework
