Hi,
You have two options:
- You use the characteristics system (one characteristic, one value of the characteristic for each line) and then set the "characteristic display method" setting of the HikaShop configuration to "list" and the "Display the quantity field on the product page" setting to "global on listings" there. That will display something like that, minus the total display, and you'll have one row per value together with its quantity field and a main add to cart button.
- You can also use the options system. In that case, you'll have one dropdown for each option (one option for each row) with in the dropdown the possibility to select the quantity for each option. The system will calculate the total with the options selected automatically with that method, but it will display as dropdowns, not with quantity fields like on your screenshot.
