Sometimes, we have to set some field to required to make sure we don't allow our end users to accidently miss answering a question. A required field will ensure the end user answers the question before they are allowed to submit the form.
To set any field to required. Simply...
- Drag the field over to the form and place it where you would like.
- Click on the "Validation" tab.
- Click the "Required" checkbox
That's it!
