Modal

Modals are a special type of overlay that shift focus towards a specific action/set of information before the main flow can proceed. They must be specified inside the overlay prop of an activator component (Button, Link or Pressable).

The library automatically applies the WAI-ARIA Dialog pattern to both the activator and the modal content.

Anchor to modalpropsModalProps

Anchor to accessibilityLabel accessibilityLabel string: A label to describe the purpose of the modal that is announced by screen readers. If not set, it will use the value of title.
Anchor to id id string: A unique identifier for the Modal. When no id is set, a globally unique value will be used instead.
Anchor to onClose onClose () => void: Callback when the modal is closed. That is when either the close button, the backdrop, or the escape key are pressed.
Anchor to onOpen onOpen () => void: Callback when the modal is opened. This is called at the beginning of the transition that opens the modal.
Anchor to padding padding boolean: Adds a default spacing around both header (which holds the title) and content of the modal.
Anchor to title title string: A title rendered at the top of the modal.

import {

useApi,

Button,

Link,

Modal,

TextBlock,

} from '@shopify/ui-extensions-react/checkout';

export default reactExtension(

'purchase.checkout.block.render',

() => <Extension />,

);

function Extension() {

const {ui} = useApi();

return (

<Link

overlay={

<Modal

id="my-modal"

padding

title="Return policy"

>

We have a 30-day return policy, which

means you have 30 days after receiving

your item to request a return.

</TextBlock>

To be eligible for a return, your item

must be in the same condition that you

received it, unworn or unused, with

tags, and in its original packaging.

You’ll also need the receipt or proof

of purchase.

ui.overlay.close('my-modal')

Anchor to best-practicesBest Practices

Use modals if:

The information needed to be shown is not critical in completing the checkout process and information cannot be condensed into one sentence.
The information the buyer is entering requires less than two rows of input fields.
The information the buyer is entering is not reliant on information on the page (which is underneath the modal and not visible to them).
