Totally understandable that sorting by an array of multiple possible values does not make sense. I am using a matching custom field as a workaround for now. I may need to come up with a custom shortcode that does the array manipulation to create something that is usable by the client.
If it’s possible somehow through a custom WP_Query, an acceptable workaround could be to just use the first taxonomy in the array of child taxonomies for each item.
This fell off the front page of threads pretty quickly. If anyone has any idea of where I should start with this, I’d really appreciate some tips.
I also have this problem using wp_list_categories(). It’s pretty annoying and makes the code look messy. Does anyone know to get rid of them?
