Conditional validation means validate a required field depending on the value of another field. In simple words when a field is hidden it wont be validated, because usually a hidden field will be kept empty.
You can omit a required field validation by using conditional rules in two ways:
- When the field is hidden.
- When the field belongs to a page that has been skipped.
So, by default the form submitter will not be able to submit the form until all required fields are completed. However, with this feature now you can submit the form without having to fill in all required fields.
Important! If you need to use Conditional Validation in your form, you just need to disable the Client-Side validation: Go to Form -> Actions -> Settings -> No Validate: ON. Then go to Conditional Rules and hide the required fields, you won’t have any problems.
