I have the following shortcode:
[mb_frontend_form id='book-photographer_relationships_to,book-publisher_relationships_to,books' post_fields="title,thumbnail" label_thumbnail="Cover" post_type="book"].
where I include 2 relationships that gives the following page https://test222.xyz/new-book/.
I want give dividers between the relationship fields in order to give consistency and readability to my form.
Can I do that?
