When set to `on` (the default), this property indicates that the field should support autofill, but you do not have any more semantic information on the intended contents. When set to `off`, you are indicating that this field contains sensitive information, or contents that are never saved, like one-time codes. Alternatively, you can provide value which describes the specific data you would like to be entered into this field during autofill. Learn more about the set of [autocomplete values](https://html.spec.whatwg.org/multipage/form-control-infrastructure.html#autofill-detail-tokens) supported in browsers. * **defaultValue** **string** The initial value of the field when it first loads. Unlike `placeholder`, this is a real value that the user can edit and that gets submitted with the form. Once the user starts typing, their input replaces this value. * **disabled** **boolean** **Default: false** Whether the field is disabled, preventing any user interaction. * **error** **string** An error message displayed below the field to indicate validation problems. When set, the field is styled with error indicators and the message is announced to screen readers. * **id** **string** A unique identifier for the element. Use this to reference the element in JavaScript, link labels to form controls, or target specific elements for styling or scripting. * **label** **string** The text displayed as the field label, which identifies the purpose of the field to users. This label is associated with the field for accessibility and helps users understand what information to provide. * **labelAccessibilityVisibility** **'visible' | 'exclusive'** **Default: 'visible'** Controls whether the label is visible to all users or only to screen readers. * `visible`: The label is shown to everyone. * `exclusive`: The label is visually hidden but still announced by screen readers. * **name** **string** The name attribute for the field, used to identify the field's value when the form is submitted. Must be unique within the nearest containing form. * **readOnly** **boolean** **Default: false** Whether the field is read-only and can't be edited. Read-only fields remain focusable and their content is announced by screen readers. * **required** **boolean** **Default: false** Whether the field needs a value. This requirement adds semantic value to the field, but it will not cause an error to appear automatically. If you want to present an error when this field is empty, you can do so with the `error` property. * **type** **'mobile' | ''** **Default: '' meaning no specific kind of phone number** The type of number to collect. Specific style may be applied to each type to provide extra guidance to users. Note that no extra validation is performed based on the type. * **value** **string** The current value for the field. If omitted, the field will be empty. ### AutocompleteSection The “section” scopes the autocomplete data that should be inserted to a specific area of the page. Commonly used when there are multiple fields with the same autocomplete needs in the same page. For example: 2 shipping address forms in the same page. ```ts `section-${string}` ``` ### AutocompleteGroup The contact information group the autocomplete data should be sourced from. ```ts "shipping" | "billing" ``` ## Events Learn more about [registering events](https://shopify.dev/docs/api/checkout-ui-extensions/2026-04/using-polaris-components#event-handling). * **blur** **CallbackEventListener\** A callback fired when the phone field loses focus. Learn more about the [blur event](https://developer.mozilla.org/en-US/docs/Web/API/Element/blur_event). * **change** **CallbackEventListener\** A callback fired when the phone field value changes. Learn more about the [change event](https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement/change_event). * **focus** **CallbackEventListener\** A callback fired when the phone field receives focus. Learn more about the [focus event](https://developer.mozilla.org/en-US/docs/Web/API/Element/focus_event). * **input** **CallbackEventListener\** A callback fired when the user inputs data into the phone field. Learn more about the [input event](https://developer.mozilla.org/en-US/docs/Web/API/Element/input_event). ### CallbackEventListener A typed event listener for custom element events. The listener receives a \`CallbackEvent\` with the correct \`currentTarget\` type for the associated custom element tag. ```ts (EventListener & { (event: CallbackEvent & TData): void; }) | null ``` ### CallbackEvent An event type that narrows the \`currentTarget\` to the specific HTML element associated with the custom element tag. This provides type-safe event handling in callback listeners. ```ts TEvent & { currentTarget: HTMLElementTagNameMap[TTagName]; } ``` ## Slots Learn more about [component slots](https://shopify.dev/docs/api/checkout-ui-extensions/2026-04/using-polaris-components#slots). * **accessory** **HTMLElement** Additional interactive content displayed within the field. Accepts button and clickable components with text content only. Other component types or complex layouts are not supported.
