Thank you for the solution provided regarding limiting the number of results; I’ll give it a try!
As for adding a link to the archive page for each post type at the end of its group, I experimented with the following code in the group-footer.php file, and it seems to be working fine:
<span>
<?php
$post_type = get_post_type($r->id);
if ($post_type === 'products') {
// If the post type is 'products', add a link to the products archive page
echo '<a href="' . home_url('/products') . '">See All Products</a>';
} elseif ($post_type === 'post') {
// If the post type is 'post', add a link to the articles archive page
echo '<a href="' . home_url('/resources') . '">See All Articles</a>';
} else {
// Otherwise, just display the post type
echo esc_html($post_type);
}
?>
</span>
It seems to do the trick for now. Let me know if there’s anything I should be cautious about with this approach!
