I try to make a view of posts belonging to a certain category but the posts from the underlying subcategories are also listed. How can I limit my view to hide the posts in subcategories and only show the posts in the current category?

I checked https://toolset.com/forums/topic/showing-products-only-in-their-sub-categories/#post-500301 but this doesn't seem to work for me.

Example page: hidden link

There's not an easy way to do this from wp-admin, but you can add the following custom code to your child theme's functions.php file:

add_filter( 'wpv_filter_query', 'only_term_filter',99,3 );
function only_term_filter( $query_args, $views_settings, $view_id) {
  $view_ids = [12345,67890];
  if (in_array($view_id, $views_ids)){
    foreach($query_args['tax_query'] as $tq) {
      if( isset( $tq['taxonomy'] ) ){
        $tax = $tq['taxonomy'];
        $term = get_term_by('id', $tq['terms'][0], $tax);
        $termChildren = get_term_children($term->term_id, $tax);
        $query_args['tax_query'][] = array(
          'taxonomy' => $tax,
          'field' => 'id',
          'terms' => $termChildren,
          'operator' => 'NOT IN'
        );
      }
    }
  }
  return $query_args;
}

Replace 12345,67890 with a comma-separated list of taxonomy View IDs where you want to apply this modification. Make sure your View's taxonomy filter is set up to respond to a shortcode attribute, something like "wpvcategory". Then pass the top-level term slug into the shortcode attribute like this:

[wpv-view name="your-view-slug" wpvcategory="parent-term"]

The View will return posts with the top-level term applied, but no posts that have to its child terms.

Thanks, I can explore a bit further now.
