Use it to collect email information in forms, customer profiles, or contact workflows. `EmailField` doesn't perform automatic email validation. Implement your own validation logic, and use the `error` property to display validation results. ## Properties Configure the following properties on the `EmailField` component. * details string The additional text to provide context or guidance for the field. This text is displayed along with the field and its label to offer more information or instructions to the user. This will also be exposed to screen reader users. * disabled boolean Default: false Whether the field is disabled, preventing user interaction. Use when the field is temporarily unavailable due to application state, permissions, or dependencies. * error string An error message to indicate a problem to the user. The field will be given specific stylistic treatment to communicate issues that must be resolved immediately. * id string A unique identifier for the element used for targeting with CSS, JavaScript, or accessibility features. * label string The content to use as the field label that describes the email information being requested. * maxLength number Default: Infinity The maximum number of characters allowed in the text field. * placeholder string A short hint that provides guidance about the expected value of the field. * required boolean Default: false Whether the field needs a value. This requirement adds semantic value to the field but doesn't cause an error to appear automatically. Use the `error` property to present validation errors. * value string The current email address entered in the field. An empty string means no email is entered. ## Slots The `EmailField` component supports slots for additional content placement within the field. Learn more about [using slots](https://shopify.dev/docs/api/polaris/using-polaris-web-components#slots). * accessory HTMLElement The additional content to be displayed in the field. Commonly used to display clickable text or action elements. Only `Button` and `Clickable` components with text content only are supported in this slot. Use the `slot="accessory"` attribute to place elements in this area. ## Events The `EmailField` component provides event callbacks for handling user interactions. Learn more about [handling events](https://shopify.dev/docs/api/polaris/using-polaris-web-components#handling-events). * blur (event: CallbackEvent<"s-email-field">) => void Called when the element loses focus. * change (event: CallbackEvent<"s-email-field">) => void Called after editing completes, typically on blur. * focus (event: CallbackEvent<"s-email-field">) => void Called when the element receives focus. * input (event: CallbackEvent<"s-email-field">) => void Called when the user makes any changes in the field. ### CallbackEvent Represents the event object passed to callback functions when interactive events occur. Contains metadata about the event, including the target element, event phase, and propagation behavior. * bubbles Whether the event bubbles up through the DOM tree. ```ts boolean ``` * cancelable Whether the event can be canceled. ```ts boolean ``` * composed Whether the event will trigger listeners outside of a shadow root. ```ts boolean ``` * currentTarget The element that the event listener is attached to. ```ts HTMLElementTagNameMap[T] ``` * detail Additional data associated with the event. ```ts any ``` * eventPhase The current phase of the event flow. ```ts number ``` * target The element that triggered the event. ```ts HTMLElementTagNameMap[T] | null ``` ```ts interface CallbackEvent { /** * The element that the event listener is attached to. */ currentTarget: HTMLElementTagNameMap[T]; /** * Whether the event bubbles up through the DOM tree. */ bubbles?: boolean; /** * Whether the event can be canceled. */ cancelable?: boolean; /** * Whether the event will trigger listeners outside of a shadow root. */ composed?: boolean; /** * Additional data associated with the event. */ detail?: any; /** * The current phase of the event flow. */ eventPhase: number; /** * The element that triggered the event. */ target: HTMLElementTagNameMap[T] | null; } ``` ### Examples * #### Capture email addresses with an email field ##### Description Capture email address input using an \`EmailField\` component. This example shows a basic email field with a label for collecting email information. ##### Default ```html ``` ## Preview ![](https://shopify.dev/images/templated-apis-screenshots/pos-ui-extensions/2025-10/email-field-default.png) ## Best practices * **Write descriptive labels:** Use specific labels like "Customer Email" or "Receipt Email Address" rather than generic "Email." * **Provide context in details:** Use `details` for additional context like "Required for digital receipts" or "We'll send order updates to this address." * **Write actionable error messages:** Provide clear validation messages like "Please enter a valid email address" that help users correct their input. ## Limitations The `accessory` slot supports only [`Button`](https://shopify.dev/docs/api/pos-ui-extensions/2025-10/polaris-web-components/actions/button) and [`Clickable`](https://shopify.dev/docs/api/pos-ui-extensions/2025-10/polaris-web-components/actions/clickable) components—other component types can't be used in the accessory slot. ## Examples Learn how to add accessory buttons and handle email input events. ### Examples * #### Add accessory buttons ##### Description Add action buttons to the email field using the accessory slot for quick actions like clearing input or verifying email addresses. This example shows how to use \[\`s-button\`]\(/docs/api/pos-ui-extensions/2025-10/polaris-web-components/actions/button) and \[\`s-clickable\`]\(/docs/api/pos-ui-extensions/2025-10/polaris-web-components/actions/clickable) components in the accessory slot, providing inline functionality within the email input context. ##### Default ```jsx console.log('Subscribe')}> Subscribe ; ``` * #### Handle email input events ##### Description Subscribe to email input events to respond when merchants enter email addresses. This example demonstrates handling \`onChange\`, \`onInput\`, \`onFocus\`, and \`onBlur\` events for real-time email validation, duplicate checking, or autosave functionality. ##### Default ```jsx console.log('Input:', event.currentTarget.value)} onChange={(event) => console.log('Change:', event.currentTarget.value)} onFocus={(event) => console.log('Focus')} onBlur={(event) => console.log('Blur')} /> ```
