Hi sakano,

Thanks for reaching out to Jotform Support. Unfortunately, our Japanese Support agents are busy helping other Jotform users at the moment. I'll try to help you in English using Google Translate, but you can reply in whichever language you feel comfortable using. Or, if you'd rather have support in Japanese, let us know and we can have them do that. But, keep in mind that you'd have to wait until they're available again.

Now, let me help you with your question. There is actually no limit for the numbers of products you can add but if you will be listing quite numbers of items, you can create categories. Let me show you how:

• In Form Builder, on the left side of the page, click on the Add Form Elements menu.
• Hover your mouse over the Product List, and drag and drop it onto your form.

• Next to the Product List, click on the List icon, and in the menu on the right side of the page, click on Settings.
• Scroll down a bit, and then toggle Enable Categories to the On position.
• Enter your category name, and click on Add.
• Repeat the process to add more new categories.

• Now in the Product List, click on the Edit icon, and enter your product details.
• In the same menu, under Select a Category, choose your category, and then click on Save. And that’s it. You’re done.

You can also check out How to Add Product Categories to Payment Fields here.

If that’s not exactly what you’re looking for, can you explain a bit more so I can help you better?
