This plugin allows you to copy values from one field to another within the same form. Values can be copied either automatically as they are typed or when a specific Checkbox in the form is checked. For example, with automatic copying the user can enter their first and last name into a field, and those values will be immediately copied into the Name input on a Credit Card field as they type.
Copying with a Checkbox is particularly useful for situations like specifying a billing and shipping address. There is a good chance the user would desire to enter the same address for both fields. You can configure a Checkbox to copy the user-entered values from the billing address field to the shipping address field.
Copy Cat supports copying to and from almost all Gravity Forms fields, so the possibilities are endless!
