Hi there!

If I understand correctly, you want to filter all tracks that have a certain condition already defined on the select.

I did something similar using: acf/fields/post_object/query (https://www.advancedcustomfields.com/resources/acf-fields-post_object-query/).

You need to a filter that will call the function that will narrow down the choices using a query.

In my case (this is OOP code but you should get the gist), I added the filter:

$action_filter_register->add_filter( 'acf/fields/post_object/query/name=client_match_object_field', Match::class, 'filter_participant_options', 10, 3 );

And then defined the function that did the trick:

	public function filter_participant_options( $args, $field, $post_id ) {
		$allowed_states = EntityStates::get_allowed_states_for_matching();
		$args['numberposts'] = -1;
		$args['meta_query']  = array(
			array(
				'key'     => '_state',
				'value'   => implode( ',', array_keys( $allowed_states ) ),
				'compare' => 'IN',
			),
		);
		return $args;
	}

Hope this helps!
