Hello Bigul,
The shortcode is a custom function to output the full list of our CPT taxonomy "categories". We used the shortcode that we created in functions.php and inserted it into the view template for our single CPT page. The list that the shortcode outputs is pre-styled and works on a number of other pages that do not use a view template.
All we did was insert the shortcode into the view template (see screenshot attached). As you saw from our original screenshots, it doesn't stay within the actual divs we setup when rendered on front end (though it's obviously inserted properly via the view template in the backend).
Thanks much!
