Features#

The HTML <dialog> element can be used to build dialogs. However, it is not yet widely supported across browsers, and building fully accessible custom dialogs from scratch is very difficult and error prone. Dialog helps achieve accessible dialogs that can be styled as needed.

Flexible – Dialogs can be used within a Modal or Popover to create many types of overlay elements.
Accessible – Exposed to assistive technology as a dialog or alertdialog with ARIA. The dialog is automatically labeled by a nested <Heading> element. Content outside the dialog is hidden from assistive technologies while it is open.
Focus management – Focus is moved into the dialog on mount, and restored to the trigger element on unmount. While open, focus is contained within the dialog, preventing the user from tabbing outside.

Anatomy#

A dialog consists of a container element and an optional title. It can be placed within a Modal or Popover, to create modal dialogs, popovers, and other types of overlays. A DialogTrigger can be used to open a dialog overlay in response to a user action, e.g. clicking a button.

import {Button, Dialog, DialogTrigger, Heading, Modal} from 'react-aria-components';

<DialogTrigger>
  <Button />
  <Modal>
    <Dialog>
      <Heading slot="title" />
    </Dialog>
  </Modal>
</DialogTrigger>

import {
  Button,
  Dialog,
  DialogTrigger,
  Heading,
  Modal
} from 'react-aria-components';

<DialogTrigger>
  <Button />
  <Modal>
    <Dialog>
      <Heading slot="title" />
    </Dialog>
  </Modal>
</DialogTrigger>

import {
  Button,
  Dialog,
  DialogTrigger,
  Heading,
  Modal
} from 'react-aria-components';

<DialogTrigger>
  <Button />
  <Modal>
    <Dialog>
      <Heading slot="title" />
    </Dialog>
  </Modal>
</DialogTrigger>

If a dialog does not have a visible heading element, an aria-label or aria-labelledby prop must be passed instead to identify the element to assistive technology.

Examples#

Destructive Alert Dialog

An animated confirmation dialog, styled with Tailwind CSS.

Gesture Driven Modal Sheet

An iOS-style gesture driven modal sheet built with Framer Motion.

Notifications Popover

A notifications popover styled with Tailwind CSS.

Starter kits#

To help kick-start your project, we offer starter kits that include example implementations of all React Aria components with various styling solutions. All components are fully styled, including support for dark mode, high contrast mode, and all UI states. Each starter comes with a pre-configured Storybook that you can experiment with, or use as a starting point for your own component library.

A Dialog may be placed within a Popover to display it in context with a trigger element.

import {OverlayArrow, Popover} from 'react-aria-components';

<DialogTrigger>
  <Button aria-label="Help">ⓘ</Button>
  <Popover>

Alert dialog#

Alert dialogs are a special type of dialog meant to present a prompt that the user must confirm before an action proceeds. An alert dialog may also behave differently with assistive technologies, such as playing a system alert sound when opening. Use the role="alertdialog" prop on the <Dialog> element to make an alert dialog.

<DialogTrigger>
  <Button>Delete…</Button>
  <Modal>
    <Dialog role="alertdialog">
      {({close}) => (
        <>
          <Heading slot="title">Delete file</Heading>
          <p>This will permanently delete the selected file. Continue?</p>
          <div style={{display: 'flex', gap: 8}}>
            <Button onPress={close}>Cancel</Button>
            <Button onPress={close}>Delete</Button>
          </div>
        </>
      )}
    </Dialog>
  </Modal>
</DialogTrigger>

Props#

DialogTrigger#

Name	Type	Description
`children`	`ReactNode`
`isOpen`	`boolean`	Whether the overlay is open by default (controlled).
`defaultOpen`	`boolean`	Whether the overlay is open by default (uncontrolled).

Events

Name	Type	Description
`onOpenChange`	`( (isOpen: boolean )) => void`	Handler that is called when the overlay's open state changes.

Dialog#

Name	Type	Description
`children`	`ReactNode \| ( (opts: DialogRenderProps )) => ReactNode`	Children of the dialog. A function may be provided to access a function to close the dialog.
`className`	`string`	The CSS className for the element.
`style`	`CSSProperties`	The inline style for the element.

Layout

Name	Type	Description
`slot`	`string \| null`	A slot name for the component. Slots allow the component to receive props from a parent component. An explicit `null` value indicates that the local props completely override all props received from a parent.

Accessibility

Name	Type	Default	Description
`role`	`'dialog' \| 'alertdialog'`	`'dialog'`	The accessibility role for the dialog.
`id`	`string`	—	The element's unique identifier. See MDN.
`aria-label`	`string`	—	Defines a string value that labels the current element.
`aria-labelledby`	`string`	—	Identifies the element (or elements) that labels the current element.
`aria-describedby`	`string`	—	Identifies the element (or elements) that describes the object.
`aria-details`	`string`	—	Identifies the element (or elements) that provide a detailed, extended description for the object.

Heading#

A <Heading> accepts all HTML attributes.

Styling#

React Aria components can be styled in many ways, including using CSS classes, inline styles, utility classes (e.g. Tailwind), CSS-in-JS (e.g. Styled Components), etc. By default, all components include a builtin className attribute which can be targeted using CSS selectors. These follow the react-aria-ComponentName naming convention.

.react-aria-Dialog {
  /* ... */
}

.react-aria-Dialog {
  /* ... */
}

.react-aria-Dialog {
  /* ... */
}

A custom className can also be specified on any component. This overrides the default className provided by React Aria with your own.

<Dialog className="my-dialog">
  {/* ... */}
</Dialog>

<Dialog className="my-dialog">
  {/* ... */}
</Dialog>

<Dialog className="my-dialog">
  {/* ... */}
</Dialog>

The selectors for each component used in a Dialog are documented below.

DialogTrigger#

The DialogTrigger component does not render any DOM elements (it only passes through its children) so it does not support styling. If you need a wrapper element, add one yourself inside the <DialogTrigger>.

<DialogTrigger>
  <div className="my-dialog-trigger">
    {/* ... */}
  </div>
</DialogTrigger>

<DialogTrigger>
  <div className="my-dialog-trigger">
    {/* ... */}
  </div>
</DialogTrigger>

<DialogTrigger>
  <div className="my-dialog-trigger">
    {/* ... */}
  </div>
</DialogTrigger>

Dialog#

A Dialog can be targeted with the .react-aria-Dialog CSS selector, or by overriding with a custom className.

Heading#

A Heading can be targeted with the .react-aria-Heading CSS selector, or by overriding with a custom className.

Advanced customization#

Custom children#

DialogTrigger and Dialog pass props to their child components, such as the trigger button and modal overlay, via their associated contexts. These contexts are exported so you can also consume them in your own custom components. This enables you to reuse existing components from your app or component library together with React Aria Components.

Component	Context	Props	Ref
`Button`	`ButtonContext`	`ButtonProps`	`HTMLButtonElement`
`Dialog`	`DialogContext`	`DialogProps`	`HTMLElement`
`Modal`	`ModalContext`	`ModalOverlayProps`	`HTMLDivElement`
`Popover`	`PopoverContext`	`PopoverProps`	`HTMLElement`
`Heading`	`HeadingContext`	`HeadingProps`	`HTMLHeadingElement`

This example consumes from HeadingContext in an existing styled heading component to make it compatible with React Aria Components. The useContextProps hook merges the local props and ref with the ones provided via context by Dialog.

import type {HeadingProps} from 'react-aria-components';
import {HeadingContext, useContextProps} from 'react-aria-components';

const MyCustomHeading = React.forwardRef(
  (props: HeadingProps, ref: React.ForwardedRef<HTMLHeadingElement>) => {
    // Merge the local props and ref with the ones provided via context.
    [props, ref] = useContextProps(props, ref, HeadingContext);
    // ... your existing Heading component
    return <h2 {...props} ref={ref} />;
  }
);

import type {HeadingProps} from 'react-aria-components';
import {
  HeadingContext,
  useContextProps
} from 'react-aria-components';

const MyCustomHeading = React.forwardRef(
  (
    props: HeadingProps,
    ref: React.ForwardedRef<HTMLHeadingElement>
  ) => {
    // Merge the local props and ref with the ones provided via context.
    [props, ref] = useContextProps(
      props,
      ref,
      HeadingContext
    );
    // ... your existing Heading component
    return <h2 {...props} ref={ref} />;
  }
);

import type {HeadingProps} from 'react-aria-components';
import {
  HeadingContext,
  useContextProps
} from 'react-aria-components';

const MyCustomHeading =
  React.forwardRef(
    (
      props:
        HeadingProps,
      ref:
        React.ForwardedRef<
          HTMLHeadingElement
        >
    ) => {
      // Merge the local props and ref with the ones provided via context.
      [props, ref] =
        useContextProps(
          props,
          ref,
          HeadingContext
        );
      // ... your existing Heading component
      return (
        <h2
          {...props}
          ref={ref}
        />
      );
    }
  );

Now you can use MyCustomHeading within a Dialog, in place of the builtin React Aria Components Heading.

<Dialog>
  <MyCustomHeading>Dialog title</MyCustomHeading>  {/* ... */}
</Dialog>

<Dialog>
  <MyCustomHeading>Dialog title</MyCustomHeading>  {/* ... */}
</Dialog>

<Dialog>
  <MyCustomHeading>
    Dialog title
  </MyCustomHeading>  {/* ... */}
</Dialog>

State#

DialogTrigger provides an OverlayTriggerState object to its children via OverlayTriggerStateContext. This can be used to access and manipulate the dialog trigger's state.

This example shows a CloseButton component that can be placed within a DialogTrigger to close the overlay.

import {OverlayTriggerStateContext} from 'react-aria-components';

function CloseButton() {
  let state = React.useContext(OverlayTriggerStateContext)!;  return <Button onPress={() => state.close()}>Close</Button>;
}

<DialogTrigger>
  <Button>About</Button>
  <Modal isDismissable>
    <Dialog>
      <Heading slot="title">About</Heading>
      <p>Copyright © 2023 Adobe. All rights reserved.</p>
      <CloseButton />    </Dialog>
  </Modal>
</DialogTrigger>

import {OverlayTriggerStateContext} from 'react-aria-components';

function CloseButton() {
  let state = React.useContext(OverlayTriggerStateContext)!;  return (
    <Button onPress={() => state.close()}>Close</Button>
  );
}

<DialogTrigger>
  <Button>About</Button>
  <Modal isDismissable>
    <Dialog>
      <Heading slot="title">About</Heading>
      <p>Copyright © 2023 Adobe. All rights reserved.</p>
      <CloseButton />    </Dialog>
  </Modal>
</DialogTrigger>

import {OverlayTriggerStateContext} from 'react-aria-components';

function CloseButton() {
  let state = React
    .useContext(
      OverlayTriggerStateContext
    )!;  return (
    <Button
      onPress={() =>
        state.close()}
    >
      Close
    </Button>
  );
}

<DialogTrigger>
  <Button>
    About
  </Button>
  <Modal isDismissable>
    <Dialog>
      <Heading slot="title">
        About
      </Heading>
      <p>
        Copyright ©
        2023 Adobe. All
        rights
        reserved.
      </p>
      <CloseButton />    </Dialog>
  </Modal>
</DialogTrigger>
