Number Field

Collect or store numeric values such as quantities or reference numbers. Learn how to create a number field with limits and validation.

A number custom field can be used for both Baskets and Option Sets. For Baskets, it appears as an input field where customers can provide additional information, such as a phone number, quantity needed or order reference number. For Option Sets, this field is visible in the admin panel within the Option Set. You can later use this information as a dynamic value in different areas, such as SKU codes or Price Codes.

Your account type and plan may limit the number of custom fields you can create.
