Button
Buttons are used primarily for actions, such as “Add”, “Close”, “Cancel”, or “Save”. Plain buttons, which look similar to links, are used for less important or less commonly used actions, such as “view shipping settings”.
Button component examples
Used most in the interface. Only use another style if a button requires more or less visual weight.
import {Button} from '@shopify/polaris';
import React from 'react';
function ButtonExample() {
return <Button>Add product</Button>;
}

Best practices
Buttons should:
- Be clearly and accurately labeled.
- Lead with a strong, actionable verb.
- Use established button colors appropriately. For example, only use a red button for an action that’s difficult or impossible to undo.
- Prioritize the most important actions. Too many calls to action can cause confusion and make merchants unsure of what to do next.
- Be positioned in consistent locations in the interface.
Buttons versus links
Buttons are used primarily for actions, such as “Add”, “Close”, “Cancel”, or “Save”. Plain buttons, which look similar to links, are used for less important or less commonly used actions, such as “view shipping settings”.
Links are used primarily for navigation, and usually appear within or directly following a sentence.
The HTML that renders for the Button and Link components carries meaning. Using these components intentionally and consistently results in:
- a more inclusive experience for assistive technology users
- a more cohesive visual experience for sighted users
- products that are easier to maintain at scale
Content guidelines
Buttons should follow the content guidelines for buttons.
Related components
- To combine or lay out multiple buttons, use the button group component
- For navigational actions that appear within or directly following a sentence, use the link component
Accessibility
Buttons can have different states that are visually and programmatically conveyed to merchants.
- Use the ariaControls prop to add an aria-controls attribute to the button. Use the attribute to point to the unique id of the content that the button manages.
- If a button expands or collapses adjacent content, then use the ariaExpanded prop to add the aria-expanded attribute to the button. Set the value to convey the current expanded (true) or collapsed (false) state of the content.
- Use the disabled prop to set the disabled state of the button. This prevents merchants from being able to interact with the button, and conveys its inactive state to assistive technologies.
- Use the pressed prop to add an aria-pressed attribute to the button.
Navigation
Merchants generally expect buttons to submit data or take action, and for links to navigate. If navigation is required for the button component, use the url prop. The control will output an anchor styled as a button, instead of a button in HTML, to help convey this difference.
For more information on making accessible links, see the link component.
Labeling
The accessibilityLabel prop adds an aria-label attribute to the button, which can be accessed by assistive technologies like screen readers. Typically, this label text replaces the visible text on the button for merchants who use assistive technology.
Use accessibilityLabel for a button if:
- The button’s visible text doesn’t adequately convey the purpose of the button to non-visual merchants
- The button has no text and relies on an icon alone to convey its purpose
To help support merchants who use speech activation software as well as sighted screen reader users, make sure that the aria-label text includes any button text that’s visible. Mismatches between visible and programmatic labeling can cause confusion, and might prevent voice recognition commands from working.
When possible, give the button visible text that clearly conveys its purpose without the use of accessibilityLabel. When no additional content is needed, duplicating the button text with accessibilityLabel isn’t necessary.
<Button>Edit shipping address</Button>
<Heading>Shipping address</Heading>
<Button accessibilityLabel="Edit shipping address">Edit</Button>
<Button accessibilityLabel="Change your shipping address">Edit</Button>
<Button accessibilityLabel="Edit">Edit</Button>
External links
When you use the button component to create a link to an external resource:
- Use the external prop to make the link open in a new tab (or window, depending on the merchant’s browser settings)
- Use the icon prop to add the external icon to the button
- Use the accessibilityLabel prop to include the warning about opening a new tab in the button text for non-visual screen reader users
For more information on making accessible links, see the link component.
<Button
accessibilityLabel="Terms and conditions (opens a new window)"
icon={ExternalIcon}
url="http://example.com"
external
>
Terms and conditions
</Button>
<Button url="http://example.com" external>Terms and conditions</Button>
<Button url="http://example.com" external>
Terms and conditions
</Button>
Keyboard support
Buttons use browser defaults for keyboard interactions.
- Give buttons keyboard focus with the tab key (or shift + tab when tabbing backwards)
- Activate buttons with the enter/return key or the space key
Custom key events
Use the onKeyDown, onKeyPress, and onKeyUp props to create custom events for buttons. With these props, you can use buttons to create complex, custom interactions like drag-and-drop interfaces.
Since these props introduce non-standard features to buttons, make sure to include accessible instructions so that merchants can understand how to use these features.
