Is there a quantity selector available for products?

Hello,

I’m sorry but I don’t fully understand your question.

Do you want to know which kind of fields you can use in a form to select quantities?
If so, you have several options like dropdowns, checkboxes or textboxes.

Please take a look at this guide: http://www.jotform.com/help/46-Quick-Overview-of-Form-Fields and see which field would fit better your needs and if you need further assistance please let us know.
We will be glad to help.

Thanks.
