Use this when the visible content alone doesn't provide enough context. * **command** **'--auto' | '--show' | '--hide' | '--toggle' | '--copy'** **Default: '--auto'** Sets the action the [`command`](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/button#command) should take when this component is activated. Available options: * `'--auto'`: Performs the default action appropriate for the target component. * `'--show'`: Displays the target component if it's currently hidden. * `'--hide'`: Conceals the target component from view. * `'--toggle'`: Alternates the target component between visible and hidden states. * `'--copy'`: Copies the target clipboard item. The supported actions vary by target component type. * **commandFor** **string** The ID of the component to control when this component is activated. Pair with the `command` property to specify what action to perform on the target component. Learn more about the [`commandFor` attribute](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/button#commandfor). * **disabled** **boolean** **Default: false** Whether the button is disabled, preventing it from being clicked or receiving focus. * **href** **string** The URL to navigate to when clicked. The `click` event fires first, then navigation occurs. If `commandFor` is also set, the command executes instead of navigation. * **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. * **inlineSize** **'auto' | 'fill' | 'fit-content'** **Default: 'auto'** The inline width of the button component. * `'auto'`: The size depends on the surface and context. * `'fill'`: The button takes up 100% of the available inline size. * `'fit-content'`: The button takes up the minimum inline size required to fit its content. * **interestFor** **string** The ID of the component to show when users hover over or focus on this component. Pair with a target component that supports interest-based interactions. Learn more about the [interestFor attribute](https://open-ui.org/components/interest-invokers.explainer/#the-pitch-in-code). * **loading** **boolean** **Default: false** Whether the button is in a loading state, which replaces the button content with a loading indicator while a background action is being performed. This also disables the button. * **target** **'auto' | '\_blank'** **Default: 'auto'** Specifies where to display the linked URL. Learn more about the [target attribute](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/a#target). * `'auto'`: Opens the URL in the current frame or a new tab, depending on the context. * `'_blank'`: Opens the URL in a new tab or window. * **tone** **'auto' | 'neutral' | 'critical'** **Default: 'auto'** The semantic meaning and color treatment of the button. * `'auto'`: Automatically determined based on context. * `'neutral'`: General information without specific intent. * `'critical'`: Urgent problems or destructive actions. * **type** **'submit' | 'button'** **Default: 'button'** The behavioral type of the button component, which determines what action it performs when activated. * `'submit'`: Submits the nearest containing form. * `'button'`: Performs no default action, relying on the `click` event handler for behavior. * `'reset'`: Resets all fields in the nearest containing form to their default values. This property is ignored if `href` or `commandFor`/`command` is set. * **variant** **'auto' | 'primary' | 'secondary'** **Default: 'auto'** The visual style variant of the button component, which controls its prominence and emphasis. * `'auto'`: Automatically determined by the button's context. * `'primary'`: High-emphasis style for the main action. * `'secondary'`: Medium-emphasis style for supporting actions. * `'tertiary'`: Low-emphasis style for less prominent actions. ## Events Learn more about [registering events](https://shopify.dev/docs/api/checkout-ui-extensions/2026-04/using-polaris-components#event-handling). * **click** **CallbackEventListener\** A callback fired when the button is clicked. This will be called before the action indicated by `type`. Learn more about the [click event](https://developer.mozilla.org/en-US/docs/Web/API/Element/click_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]; } ``` Examples ## Preview ![](https://cdn.shopify.com/shopifycloud/shopify-dev/development/assets/assets/images/templated-apis-screenshots/checkout-ui-extensions/2025-10/button-default-BNP27v3f.png) ### Examples * #### Code ##### Default ```html Cancel Save ``` ## Best Practices **Content Best Practices** * Clearly label each button to accurately represent the action associated with it. * Use strong actionable verbs at the beginning of button text to make it clear to the user what action will occur when the button is clicked. **Hierarchy Best Practices** * Establish a visual hierarchy between buttons to minimize confusion and help users understand which actions are most important. * Use only one high-emphasis button (primary button) per context to make it clear that other buttons have less importance. * Use lower-emphasis buttons for secondary calls to action. * Use primary buttons for actions that progress users through checkout such as “Pay now” or for concluding an action in a modal such as “Apply”. * Use secondary buttons to provide alternative actions to the primary button, without disrupting the primary flow such as “Track your order”. **When to Use Buttons** * Use buttons to communicate actions the user can take. * Use buttons to allow users to interact with the page. **When Not to Use Buttons** * Don’t use buttons as navigational elements. Use links instead when the desired action is to take the user to a new page.
