Hello, I would like to add extra fields as shown in the attachment. I'm using Dokan Pro, and I want sellers to be able to add custom extra prices and options they define themselves on their product submission pages, just like in the image. For example, if it's a restaurant selling hamburgers, I want them to be able to add options like extra ketchup, hot sauce, etc., along with their respective prices. If you could assist me on how to achieve this, I would appreciate it. https://tinypic.host/images/2023/08/28/IMG_3722.png
