Hi support originally helped me with this ticket "Create a grid of parent posts, with lists child posts for each parent" -
https://toolset.com/forums/topic/parent-child-posts-display-all/ Basically creating a grid of parent posts with their child posts underneath (see grid.png screenshot)

which worked perfectly. I've since come up against a slight problem. I hadn't anticipated that there would be some parent posts which didn't have any child posts. In that case the grid shows the standard "no items found" text which looks a bit odd. Is it possible to hide the parent AND child if the parent has no children.

Hello. Thank you for contacting the Toolset support.

Yes, its possible but I would like to review how you setup your nested views.

Can you please share problem URL where you added the parent/child grid as well as access details.

*** Please make a FULL BACKUP of your database and website.***
I would also eventually need to request temporary access (WP-Admin and FTP) to your site. Preferably to a test site where the problem has been replicated if possible in order to be of better help and check if some configurations might need to be changed.

I have set the next reply to private which means only you and I have access to it.

Can you please check now: hidden link

I've added the following shortcode "get-related-post-count" that will help us to find out if there is any child post available for the parent in loop to "Custom Code" section offered by Toolset:
=> hidden link

add_shortcode( 'get-related-post-count', function( $atts = [] ){
   
    // provide defaults
    $atts = shortcode_atts( 
        array(
            'relationship'      =>   '',
        ), 
        $atts
    );
   
    global $post;
    $count = 0;
   
    $relationship = toolset_get_relationship( $atts['relationship'] );
   
    if ( $relationship ) {
   
        $parent = $relationship['roles']['parent']['types'][0];
        $child = $relationship['roles']['child']['types'][0];
        $type = $post->post_type;
   
        $origin = ( $parent == $type ) ? 'parent' : 'child';
   
        // Get connected posts
        $connections = toolset_get_related_posts( $post->ID, $atts['relationship'], array(
            'query_by_role' => $origin,
            'role_to_return' => 'other',
            'need_found_rows' => true )
        );
        $count = $connections['found_rows'];
   
    }
   
    return $count;
});

- I've register the above shortcode "get-related-post-count" at:
=> Toolset => Settings => Front-end Content => Third-party shortcode arguments

And used the above shortcode as given under within the "FAQs Directory" view's loop editor section:
=> => hidden link

<div class="row mb-5">
	<wpv-loop>
		  [wpv-conditional if="( '[get-related-post-count relationship='service-faq']' gt '0' )"]
          	<div class="col-md-3">[wpv-post-body view_template="loop-item-in-faqs-directory"]</div>
          [/wpv-conditional]
          
	</wpv-loop>
  </div>

And also modified how you added the child view to "FAQs Directory" view:

[wpv-view name="child-faqs-directory" postid="[wpv-post-id]"]

And within the child view, i've catch the postid shortcode argument as given under:
=> hidden link

<h4>[wpv-post-link item='[wpv-attribute name="postid"]']</h4>

I can see its working as expected. Can you please confirm.
