Hide empty categories in shortcode

Hi,

you can hide the empty categories by adding the below code snippet in your theme functions.php file (or even better by creating a new blank plugin and pasting the code there https://wpadverts.com/blog/how-to-use-code-snippets-in-wordpress/)

add_filter( "adverts_categories_query", function( $args ) {
  $args["hide_empty"] = 1;
  return $args;
} );

For sub-categories you will need another code snippet

add_filter( "adverts_categories_query_sub", function( $args ) {
  $args["hide_empty"] = 1;
  return $args;
} );
