Conditional validation for view builder
A system for conditional validation in forms includes at least one processor, and at least one memory coupled to the at least one processor and configured to store executable instructions. The executable instructions, when executed by the at least one processor, cause the at least one processor to visually present a plurality of parameters for defining at least one condition for controlling a property of a first field of a form in a configuration mode, generate a condition corresponding to a set of user inputs for the plurality of parameters, and store the generated condition with the form. The condition is based on a second field different from the first field.
1. A system for conditional validation in forms, the system comprising:
