Every field has 5 configuration tabs when clicked on the form canvas:
| Tab | What you configure |

| Design | Question text, description, placeholder, help text |

Using in workflows
When this field is part of a form connected to a workflow via the Form Submission trigger, its value is available as a variable:
{{trigger.fieldName}}
Use it in any downstream node: send it in an email, store it in a database, pass it to an AI node for analysis, or use it in an If-Else condition for routing.
