# Modal
Modals are overlays that prevent merchants from interacting with the rest of the application until a specific action is taken. They can be disruptive because they require merchants to take an action before they can continue interacting with the rest of Shopify. It should be used thoughtfully and sparingly.
---
## Use in an embedded application (deprecated)
Passing an API key to the [app provider component](https://polaris.shopify.com/components/structure/app-provider#section-initializing-the-shopify-app-bridge) causes the modal component to delegate to the [Shopify App Bridge](https://help.shopify.com/en/api/embedded-apps/app-bridge) instead of rendering as it would in a stand-alone application.
In an embedded application context, not all documented properties are available. Some properties are only available in stand-alone applications.
Properties that are available only in a stand-alone context are documented as `(stand-alone app use only)`. For instance the `children` property is documented as `(stand-alone app use only)`.
The following example shows the modal component in an embedded application context:
```jsx
class EmbeddedAppModalExample extends React.Component {
state = {
modalOpen: false,
};
render() {
return (
<AppProvider apiKey="YOUR_API_KEY" i18n={{}}>
<Modal
src="https://my-app.com/upgrade-to-retail-package"
open={this.state.modalOpen}
title="Upgrade your Shopify POS with the Retail Package"
primaryAction={{
content: 'Add Retail Package',
onAction: () => this.setState({modalOpen: false}),
}}
secondaryActions={[
{
content: 'Cancel',
onAction: () => this.setState({modalOpen: false}),
},
]}
onClose={() => this.setState({modalOpen: false})}
/>
</AppProvider>
);
}
}
```
#### Deprecation rationale
As of v3.17.0, using `Modal` in an embedded app is deprecated. Support for this will be removed in v5.0 as the underlying Shopify App Bridge library will be removed from Polaris React. More information can be found [here](https://github.com/Shopify/polaris-react/issues/814). Use `Modal` from `@shopify/app-bridge-react` instead. For example, `import {Modal} from '@shopify/app-bridge-react';`.
---
## Best practices
Modals should:
- Only be closed by clicking the `X` or `Cancel` button and not by clicking the backdrop outside the modal, which is a large touch target that could result in accidental presses. Modals require merchants to take an action and should prevent the merchant from accidentally closing the modal without completing the required task.
- Avoid having more than two buttons (primary and secondary) at the bottom. This prevents unclear action hierarchy and crowding on mobile screens. Since modals are for focused tasks, they should have focused actions. In some cases however, a [tertiary action](#tertiary-actions) may be appropriate.
---
## Content guidelines
### Title
Titles should be:
- Informative and descriptive
- They should label the type of content grouped in the modal
- Use a clear {verb}+{noun} question
- Concise and scannable:
- Use simple, clear language that can be read at a glance
- Keep headings to single sentence and avoid using punctuation such as periods, commas, or semicolons
- Avoid articles (the, a, an) in [microcopy headings](/content/grammar-and-mechanics#section-headings-and-subheadings) to keep content short and actionable
- Written in sentence case (first word capitalized, the rest is lowercase)
<!-- usagelist -->
#### Do
- Edit email address
- Delete customer?
- Discard unsaved changes?
#### Don’t
- Edit the email address for this order
- Are you sure you want to delete customer?
- Discard?
<!-- end -->
### Body content
Body content should be:
- Actionable: start sentences with imperative verbs when telling a merchant what actions are available to them (especially something new). Don’t use permissive language like "you can".
<!-- usagelist -->
#### Do
- Notification emails will be sent to this address.
- This can’t be undone.
#### Don’t
- You can edit the email address where emails will be sent.
- Are you sure you want to delete the variant Dark Blue Tee/Small/Silk? You cannot reverse this.
<!-- end -->
- Structured for merchant success: always put the most critical information first.
- Clear: use the verb “need” to help merchants understand when they’re required to do something.
<!-- usagelist -->
#### Do
- To buy a shipping label, you need to enter the total weight of your shipment, including packaging.
#### Don’t
- To buy a shipping label, you must enter the total weight of your shipment, including packaging.
<!-- end -->
### Primary and secondary actions
Actions should be:
- Clear and predictable: merchants should be able to anticipate what will happen when they click a button. Never deceive a merchant by mislabeling an action.
<!-- usagelist -->
#### Do
- Create order
- Buy shipping label
#### Don’t
- New order
- Buy
<!-- end -->
- Action-led: actions should always lead with a strong verb that encourages action. To provide enough context to merchants use the {verb}+{noun} format on actions except in the case of common actions like Save, Close, Cancel, or OK.
<!-- usagelist -->
#### Do
- Activate Apple Pay
- View shipping settings
#### Don’t
- Try Apple Pay
- View your settings
<!-- end -->
- Scannable: avoid unnecessary words and articles such as the, an, or a.
<!-- usagelist -->
#### Do
- Add menu item
#### Don’t
- Add a menu item
<!-- end -->
<a name="tertiary-actions"></a>
### Tertiary actions
Tertiary actions should:
- Only be used when the action requires the context of the content in the modal
- Never be used to dismiss the modal
<!-- usagelist -->
#### Do
- Use a plain button for a tertiary action if needed
#### Don’t
- Use a tertiary action for a destructive action
<!-- end -->
### Footer
Body content should be:
- Actionable: start sentences with imperative verbs when telling a merchant what actions are available to them (especially something new). Don’t use permissive language like "you can".
<!-- usagelist -->
#### Do
- Notification emails will be sent to this address.
#### Don’t
- You can edit the email address where emails will be sent.
<!-- end -->
- Structured for merchant success: always put the most critical information first.
- Clear: use the verb “need” to help merchants understand when they’re required to do something.
<!-- usagelist -->
#### Do
- To buy a shipping label, you need to enter the total weight of your shipment, including packaging.
#### Don’t
- To buy a shipping label, you must enter the total weight of your shipment, including packaging.
<!-- end -->

## Examples
### Basic modal
<!-- example-for: web -->
Use as the default option for a modal.
```jsx
class ModalExample extends React.Component {
state = {
active: true,
};
render() {
const {active} = this.state;
return (
<div style={{height: '500px'}}>
<Button onClick={this.handleChange}>Open</Button>
<Modal
open={active}
onClose={this.handleChange}
title="Reach more shoppers with Instagram product tags"
primaryAction={{
content: 'Add Instagram',
onAction: this.handleChange,
}}
secondaryActions={[
{
content: 'Learn more',
onAction: this.handleChange,
},
]}
>
<Modal.Section>
<TextContainer>
<p>
Use Instagram posts to share your products with millions of
people. Let shoppers buy from your store without leaving
Instagram.
</p>
</TextContainer>
</Modal.Section>
</Modal>
</div>
);
}
handleChange = () => {
this.setState(({active}) => ({active: !active}));
};
}
```
### Modal with primary action
Use to let merchants take a key action.
```jsx
const DISCOUNT_LINK = 'https://polaris.shopify.com/';
class ModalExample extends React.Component {
state = {
active: true,
};
node = null;
render() {
const {active} = this.state;
return (
<div style={{height: '500px'}}>
<Button onClick={this.toggleModal}>Open</Button>
<Modal
open={active}
onClose={this.toggleModal}
title="Get a shareable link"
primaryAction={{
content: 'Close',
onAction: this.toggleModal,
}}
>
<Modal.Section>
<Stack>
<Stack.Item>
<TextContainer>
<p>
You can share this discount link with your customers via
email or social media. Your discount will be automatically
applied at checkout.
</p>
</TextContainer>
</Stack.Item>
<Stack.Item fill>
<TextField
ref={this.bindNode}
label="Discount link"
onFocus={this.handleFocus}
value={DISCOUNT_LINK}
onChange={() => {}}
connectedRight={
<Button primary onClick={this.handleClick}>
Copy link
</Button>
}
/>
</Stack.Item>
</Stack>
</Modal.Section>
</Modal>
</div>
);
}
handleClick = () => {
if (this.node == null) {
return;
}
this.node.input.focus();
};
handleFocus = () => {
if (this.node == null) {
return;
}
this.node.input.select();
document.execCommand('copy');
};
toggleModal = () => {
this.setState(({active}) => ({active: !active}));
};
bindNode = (node) => {
if (node == null) {
return;
}
this.node = node;
};
}
```

### Modal with primary and secondary actions
Use to let merchants take key actions at the bottom of the modal.
```jsx
const CURRENT_PAGE = 'current_page';
const ALL_CUSTOMERS = 'all_customers';
const SELECTED_CUSTOMERS = 'selected_customers';
const CSV_EXCEL = 'csv_excel';
const CSV_PLAIN = 'csv_plain';
class ModalExample extends React.Component {
state = {
active: true,
selectedExport: [],
selectedExportAs: [],
};
render() {
const {active, selectedExport, selectedExportAs} = this.state;
return (
<div style={{height: '500px'}}>
<Button onClick={this.handleModalChange}>Open</Button>
<Modal
open={active}
onClose={this.handleClose}
title="Export customers"
primaryAction={{
content: 'Export customers',
onAction: this.handleClose,
}}
secondaryActions={[
{
content: 'Cancel',
onAction: this.handleClose,
},
]}
>
<Modal.Section>
<Stack vertical>
<Stack.Item>
<ChoiceList
title={'Export'}
choices={[
{label: 'Current page', value: CURRENT_PAGE},
{label: 'All customers', value: ALL_CUSTOMERS},
{label: 'Selected customers', value: SELECTED_CUSTOMERS},
]}
selected={selectedExport}
onChange={this.handleCheckboxChange('selectedExport')}
/>
</Stack.Item>
<Stack.Item>
<ChoiceList
title={'Export as'}
choices={[
{
label:
'CSV for Excel, Numbers, or other spreadsheet programs',
value: CSV_EXCEL,
},
{label: 'Plain CSV file', value: CSV_PLAIN},
]}
selected={selectedExportAs}
onChange={this.handleCheckboxChange('selectedExportAs')}
/>
</Stack.Item>
</Stack>
</Modal.Section>
</Modal>
</div>
);
}
handleModalChange = () => {
this.setState(({active}) => ({active: !active}));
};
handleClose = () => {
this.setState(({active}) => ({
active: !active,
selectedExport: [],
selectedExportAs: [],
}));
};
handleCheckboxChange = (key) => {
return (value) => this.setState({[key]: value});
};
}
```

### Large modal
<!-- example-for: web -->
Use when you need to increase the width of your modal.
```jsx
class ModalExample extends React.Component {
state = {
active: true,
checked: false,
};
render() {
const {active, checked} = this.state;
return (
<div style={{height: '500px'}}>
<Button onClick={this.handleChange}>Open</Button>
<Modal
large
open={active}
onClose={this.handleChange}
title="Import customers by CSV"
primaryAction={{
content: 'Import customers',
onAction: this.handleChange,
}}
secondaryActions={[
{
content: 'Cancel',
onAction: this.handleChange,
},
]}
>
<Modal.Section>
<Stack vertical>
<DropZone
accept=".csv"
errorOverlayText="File type must be .csv"
type="file"
onDrop={() => {}}
>
<DropZone.FileUpload />
</DropZone>
<Checkbox
checked={checked}
label="Overwrite existing customers that have the same email or phone"
onChange={this.handleCheckbox}
/>
</Stack>
</Modal.Section>
</Modal>
</div>
);
}
handleChange = () => {
this.setState(({active}) => ({active: !active}));
};
handleCheckbox = (value) => {
this.setState({checked: value});
};
}
```
### Modal without a title
<!-- example-for: web -->
We recommend you add a title to your modal, but you may leave it blank.
```jsx
class ModalExample extends React.Component {
state = {
active: true,
};
render() {
const {active} = this.state;
return (
<div style={{height: '500px'}}>
<Button onClick={this.handleChange}>Open</Button>
<Modal
open={active}
onClose={this.handleChange}
primaryAction={{
content: 'Add Instagram',
onAction: this.handleChange,
}}
secondaryActions={[
{
content: 'Learn more',
onAction: this.handleChange,
},
]}
>
<Modal.Section>
<TextContainer>
<p>
Use Instagram posts to share your products with millions of
people. Let shoppers buy from your store without leaving
Instagram.
</p>
</TextContainer>
</Modal.Section>
</Modal>
</div>
);
}
handleChange = () => {
this.setState(({active}) => ({active: !active}));
};
}
```
### Modal with scroll listener
<!-- example-for: web -->
Use to implement infinite scroll of modal content.
```jsx
class ModalExample extends React.Component {
state = {
active: true,
};
render() {
const {active} = this.state;
return (
<div style={{height: '500px'}}>
<Button onClick={this.handleChange}>Open</Button>
<Modal
open
title="Scrollable content"
onClose={this.toggleModalVisibility}
onScrolledToBottom={() => alert('Scrolled to bottom')}
>
{Array.from({length: 50}, (_, index) => (
<Modal.Section key={index}>
<TextContainer>
<p>Item #{index}</p>
</TextContainer>
</Modal.Section>
))}
</Modal>
</div>
);
}
toggleModalVisibility = () => {
this.setState(({active}) => ({active: !active}));
};
}
```
### Warning modal
<!-- example-for: android, ios -->
Use to make it clear to the merchant that the action is potentially dangerous. Only use this option when the merchant is about to perform an action that can’t be undone or is difficult to undo.
