Allows only one product with multiple quantity in Cart page

Hello,

So far, there are no options in HikaShop to do that, now maybe we can offer you some solutions, but for this you have to details more your needs and purpose.
More clearly, can you provide these elements :
- An Url link to better understand the context.
- Several concretes examples to explain us what you expect from your cart.
- Does this way to process have to be only for one product vs others, or does there are other product categories ?
- Description of your needs, and the reason of these specific needs

Be more detailed and precise as possible will allow us to find solutions together.
Regards
