How to add a field condition
The form inputs for advanced forms have a Field Condition tab to set a field as required or read-only based on a condition. Making a field required can prevent errors and is helpful when a form needs to comply with legal and regulatory standards. Whereas making a field read-only is useful when integrating with another product and you need to display data to users but don't want them to change it, such as an account number.
For example, you have a form with a lookup of different type of discounts you offer customers. When Military is selected as the discount type, you require a photo of the military ID. A condition could be set up on a media field so that when Military is the selected discount type, the media field is required.
Using the same example your form also has a number field to enter the discount percentage. When Cash is the selected discount, you want app users to use the discount set up in your back office and not be able to change it. A condition could be set up on the number field so that when Cash is the selected discount type, the number field is read-only.
