Text Input

The Text input component is an input field that allows users to enter information inside. You can:

• Navigate using mouse and keyboard with arrow and letter keys.
• Enter text using either a physical or a virtual keyboard. When using the virtual keyboard, the input selector allows you to enter letters and numbers.

Example

You can use the Text input component to create an app to modify your customer information. In this example:

• Users can view the Customer ID in the Text input component.
• Users can edit the Short name in the Text input component.

Note: The Text input component follows the WCAG 2.0 AA accessibility guidelines. See the Properties section for accessibility configuration tips.

Configuration example

This example shows how to configure the Customers app (see Example of usage). Follow these steps to configure it:

• Drag the Text input component to a previously added Layout component in the canvas.

• Select the Text input component in the canvas and go to the Properties panel.

• Open the Main menu and configure:

  • Component ID: Enter a meaningful name and select the Save button. See templating in components for more details.

  • Label: Enter the text you want to appear above your text field. This example shows Customers ID above the first text input and Short name above the second. See the Properties section for accessibility information.

  • Placeholder: Enter a text that provides a hint for the expected input. This example shows Customer ID in the first text input and Short name in the second. Read the Properties section for accessibility information.

  • Default value: You can choose a value to be displayed by default. For this example:

    • Customer ID text input: To pre-fill the text input with the selection made by the user in the Customer Name selector of the app, follow these steps:

      1. Select the Plus (+) button.
      2. Go to Fields and open the menu.
      3. Select the data you want to display. In this example, we select value, which refers to the input of the Customer name selector where we have used {{customerId}}. As a result, the corresponding customer ID is displayed in the Text input component. See Templating dropdown for more details.

    

    • Short name text input: To pre-fill the text input with the short name of the customer selected by the user, you need to create another resource to make a call to the necessary API. After creating the resource, retrieve the data using Liquid. You have two options: select the data from the dropdown displayed by selecting the Plus (+) button or enter the data manually, for this example {{res2.aliasName}}.

  Note: You must edit all your resources in the Resource tab. See resources for more details.

• Open the Validation menu and configure:

  • Customer ID text input: Keep the default settings.
  • Short name text input: To make the field mandatory, you must turn on the Required field switch and leave all the other options in their default settings.

• Open the Interactions menu and configure:

  • Customer ID text input: Select the Read only checkbox. We want the field to always be read only so we do not add any rules.
  • Short name text input: Select the Read only checkbox and add a rule so it is set to read only until a customer is selected in the Customer name selector. Enter the rule in Liquid, for this example {{customer.value == ""}}, where customer corresponds to the Component ID of the Customer name selector. This rule reads: if the customer value is an empty string, set the component to read only. See add rules to trigger properties for more details.

Note: Only the properties relevant to the example are explained. See the Properties section for more details.
