Text area

It is an important tool for creating intuitive and effective conversational interfaces that can collect and process large amounts of user input.

​

Configuring the text area element

​

Text area generic settings

These settings added in the Generic tab are available and they apply to all platforms including Web, iOS, and Android:

• Process data key
• Properties
• Datasource
• Validators
• Expressions
• UI actions
• Text area styling

​

Prcoess data key

Process data key creates the binding between form element and process data, so it can be later used in decisions, business rules or integrations

​

Properties

• Label: The visible label for the text area element.
• Placeholder: Text that appears within the text area when it is empty.
• Has Clear: Option to include a content clear mechanism.
• Helpertext: Additional information about the text area field (can be hidden inside an infopoint).
• Update on Blur: Update behavior triggered when the text area loses focus.

​

Datasource configuration

The default value for the element can be configured here, this will autofill the text field when you will run the process.

​

Validators

You can add multiple validators to a text area field. For more details, refer to Validators.

​

Hide/disable expressions

The text area’s behavior can be defined using JavaScript expressions for hiding or disabling the element. The following properties can be configured for expressions:

• Hide condition: A JavaScript expression used to hide the text area when it is evaluated to your desired result.
• Disabled condition: A JavaScript expression used to disable the text area when it returns a truthy value

​

Hide expression example

We will use the key defined on the switch element to create a JavaScript hide condition to hide the text area element:

• Rule used:

${application.client.hasHouse} === false

• Result:

​

Disable example

For example, you can use a disabled condition to disable a text area element based on what values you have on other elements.

When you choose a specific value on the radio element (Contact via SMS), the text area is disabled based on the disabled condition.

• Rule used:

${application.client.contact} == "prfS"

​

UI actions

UI actions can be added to the text area field to define its behavior and interactions.

• Event: Possible value - CHANGE.
• Action Type: Select the type of the action to be performed.

​

Text area settings overrides

There are instances where you may need to tailor settings configured in the Generic settings tab. This proves especially beneficial when you wish to adjust these settings to appear differently across various platforms such as Web, Android, or iOS.

Available override settings:

• Properties:
  • Label: Override the text area label.
  • Helper: Override helper text/info point.
  • Placeholder: Override the placeholder.
