Supposed that you've already created a form using Blue Form Builder.
- In the form builder section, hover over an element, then click Edit to open the settings popup.
- Open Validation tab and you'll find Validation drop-down where you can choose your desired option.
Note: Some elements have been already set validation so you don't need to do this, for example: Email element, Phone Element.
