🔁 Conditional Display Logic

You can make fields appear based on another field's value using:

• dependsOn: key of the controlling field
• showIf: comma-separated list of values to match (* = any value)

Example:

{
  key: "state",
  label: "State",
  type: "text",
  dependsOn: "country",
  showIf: "USA,Canada"
}
