With 123FormBuilder, form branching and conditional logic is very easy to set up. Each field rule can have multiple conditions and multiple results. By setting up a single rule that affects multiple fields instead of repeating that rule for each affected field, you save a lot of time.
To add multiple results to a field rule, go to the Settings → Rules section and click on Add Rule.
The first half of the rule represents the condition. The second half of the rule represents the result.
Check the fields that you want or use the option Check all to select all fields. Click Finished and you’re done.
The same fields can not be used in two separate rules after THEN. This will cause a rule conflict.
