Description - It would be great to have validations on custom forms. Like set up basic rules like triggering client side error while filling up info in the form for the text fields. For example to capture email ID to have @ and . in the text else generate the eror for correcting the format of the input field.
Why is this feature important to you - It would help greatly in cllecting correct data in the forms. Validations are basic requiremenst to have some valuable data being collected in the any form.
How would you like the feature to work - Just like Display logic, have a sset rule on fields to allow us set up validation rules.
Current Behaviour - There is no such way to apply any kind of validation.
