Can I have a user input field in a table that is linked to a dataset?

I have a table linked to a dataset of ingredients,
I have set filters to show the different types of ingredients.
Id now like to add a quantity field where members can go through the list adding quantities.these quantities will be attached to the ingredient and when a submit button is clicked will create a new list showing what they have chosen, Idealy this new list will be available as a PDF to email to a supplier… is this possible?

Hello,

In order to implement this, I would recommend creating a custom form.
Custom Forms

In order to contact your suppliers, you can use Triggered Emails.
