Text area

A text area allowing the user to read and edit multiline textual data.

Configurable properties

• Field label: Label displayed on top of the text area. Can either be an expression, plain text, or templating syntax.
• Field description: Description provided below the text area. Can either be an expression, plain text, or templating syntax.
• Key: Binds the field to a form variable, refer to data binding docs.
• Default value: Provides a default value for the text area in case no input data exists for the given key.
• Read only: Makes the text area read-only, meaning the user can't change but only read its state. Can be dynamically set using an expression.
• Disabled: Disables the text area; for use during development.
• Hide if: Expression to hide the text area.
• Columns: Space the field will use inside its row. Auto means it will automatically adjust to available space in the row. Read more about the underlying grid layout in the Carbon Grid documentation.
• Validation: Given that one of the following properties is set, the form will only submit when the respective condition is fulfilled. Otherwise, a validation error will be displayed.
  • Required: Text area must contain a value.
  • Minimum length: Text area must have at least n characters.
  • Maximum length: Text area must not have more than n characters.

Datatypes

Text area can be bound to boolean, string, and number data, but will coerce the data into a string, which will lead the data to be written back to the process as a string when the form is submitted.
