Product Quantity Increments


Quantities of items that user may add to my website could be over 200. Snipcart panel allows me to increment/decrement one by one. Can you imagine a user needs to click 200 times when editing a cart? How can we alter the form field, so the user enters a quantity number on a keyboard, a dropdown? Or do you have another solution?

I can add the right qty of products from the frontend. But if a user changes mind of qty, again, they will need to have a click for each increment of one. Very bad UX. Please help
