Migrate to Polaris

Version 2025-07 is the last API version to support React-based UI components. Later versions use web components, native UI elements with built-in accessibility, better performance, and consistent styling with Shopify's design system. Check out the migration guide to upgrade your extension.

Choose a version:

TextField

The TextField component captures single-line text input. Use it to collect short, free-form information in forms and data entry workflows.

The component supports various input configurations including placeholders, character limits, and validation. It includes built-in support for labels, helper text, and error states to guide merchants through data entry, ensuring accurate and efficient information capture across different retail scenarios.

Anchor to PropertiesProperties

Configure the following properties on the TextField component.

Anchor to label label string required: The content to use as the field label that describes the text information being requested.
Anchor to action action: A button configuration object displayed under the text field to provide extra functionality.
Anchor to disabled disabled boolean: Controls whether the field can be modified. When true, the field is disabled and users cannot edit its value.
Anchor to error error string: An error message that indicates a problem to the user. The field is given specific stylistic treatment to communicate issues that must be resolved immediately.
Anchor to helpText helpText string: The label text displayed under the field that provides guidance or instructions to assist users.
Anchor to maxLength maxLength number: The maximum number of characters allowed in the text field.
Anchor to onBlur onBlur () => void: A callback function executed when focus is removed from the field.
Anchor to onChange onChange (value: string) => void: A callback function executed when the user has finished editing the field, receiving the new text value as a parameter. You should update the value property in response to this callback.
Anchor to onFocus onFocus () => void: A callback function executed when the field receives focus.
Anchor to onInput onInput (value: string) => void: A callback function executed immediately when the user makes any change in the field. Use this for real-time feedback, such as clearing validation errors as soon as the user begins making corrections. Don't use this to update the value property—the onChange callback is the appropriate handler for updating the field's value.
Anchor to placeholder placeholder string: A short hint that describes the expected value of the field.
Anchor to required required boolean: A boolean that indicates whether the field needs a value for form submission or validation purposes.
Anchor to value value string: The current text value for the field. If omitted, the field will be empty. You should update the value property in response to the onChange callback.

InputAction

Defines the configuration object for action buttons displayed below input fields to provide extra functionality.

disabled
A boolean value that determines whether the action button can be pressed.
```
boolean
```
label
The text displayed on the action button.
```
string
```
onPress
A callback function executed when the action button is pressed.
```
() => void
```

Anchor to Best practicesBest practices

Set initial focus appropriately: When merchants open a new form, set focus on the first text field automatically to streamline data entry and reduce the number of interactions required to begin input.
Write clear and concise labels: Write labels in sentence case and keep them brief. Use consistent terminology for similar fields throughout the app to create a predictable and familiar experience for merchants.
Indicate required fields clearly: When a text field is required for form submission, use the required property and display a "Required" indicator. Implement validation logic in your onChange callback to check empty values and display errors.
Provide helpful guidance with helpText and placeholder: Use helpText for explain content expectations, formatting requirements, or character limits. Use placeholder text to provide examples of the expected content format or structure.
Support autocomplete when appropriate: Provide autocomplete options for fields where merchants commonly enter predictable values, such as addresses, product names, or customer information.
Implement character limits appropriately: Set maxLength to prevent excessively long input that might cause display or processing issues. Provide feedback about character limits in the helpText, especially when users are approaching the limit.
Use action buttons for enhanced functionality: Use the action property to provide helpful actions like "Clear Field," "Generate Code," or "Use Default." This enhances usability by providing quick access to common text operations.

Anchor to LimitationsLimitations

TextField provides single-line text input only—multi-line text entry requires the TextArea component.
The required property adds semantic meaning only—it doesn't trigger automatic error display or validation, so you must implement validation logic manually.
Action buttons are limited to simple press callbacks—complex action workflows require custom implementation or additional components.
