You may create a category in your product listing and add products .

If you're referring to something else, kindly explain further how you would like to setup your categories?

Looking forward for your response.

What I was asking is as follows:
In my iphone square pos app I can select favorites in the checkout tab. I see a grid with empty boxes. My question is, how can I fill the grid with my categories so that when I select a grid it will show the items in that grid category.
...

Unfortunately, we don't have such feature in our payment integration JotForm.

We can however select categories on our products.

That’s what I thought. Thanks for the speedy response
