User defined fields can be added to a DIY form to capture additional information about your donors such as interests, tribute information, etc...
Can user defined fields be made conditional so that they only appear when certain requirements are met?
For example, hiding a set of tribute fields unless the donor indicates their donation is a tribute donation, at which point the tribute fields are made visible.
This is not possible at this time with DIY Forms. eTapestry's eCommerce team can create a custom form that has this functionality, however. For more information on a custom form, please contact your account executive.
