Hello,
I see, so to show the short description on the shop page under the product title, you first need to create the custom shop page from Porto >> Template Builder >> Product Archives, You have to use the “Type Builder Archive” element, and when you edit that element you will find the option to choose the “Post Layout”: https://postimg.cc/1nKPNy3V
Now before choosing the post layout, you have to create it, and for that you need to navigate to Porto >> Template Builder >> Post Type, create the new post type from there, whether import using studio, or create the custom, then use “Woo short description” element at any place as per your requirements, please refer to this screenshot: https://postimg.cc/754VKDHZ
