Add text under categories products

To display the text on the category page below the products, you need to add this code to the functions.php file in the child theme so this code is not overwritten on an update.

You will get an additional field in the category properties named “Details”. Add your article here and you will get the text underneath the products list on category page. This will work for each category.
