Dialog

A window overlaid on either the primary window or another dialog window, rendering the content underneath inert.

import React from 'react';
import * as Dialog from '@radix-ui/react-dialog';
import { Cross2Icon } from '@radix-ui/react-icons';
import './styles.css';

const DialogDemo = () => (
  <Dialog.Root>
    <Dialog.Trigger asChild>
      <button className="Button violet">Edit profile</button>
    </Dialog.Trigger>
    <Dialog.Portal>
      <Dialog.Overlay className="DialogOverlay" />
      <Dialog.Content className="DialogContent">
        <Dialog.Title className="DialogTitle">Edit profile</Dialog.Title>
        <Dialog.Description className="DialogDescription">
          Make changes to your profile here. Click save when you're done.
        </Dialog.Description>
        <fieldset className="Fieldset">
          <label className="Label" htmlFor="name">
            Name
          </label>
          <input className="Input" id="name" defaultValue="Pedro Duarte" />
        </fieldset>
        <fieldset className="Fieldset">

          </label>
          <input className="Input" id="username" defaultValue="@peduarte" />
        </fieldset>
        <div style={{ display: 'flex', marginTop: 25, justifyContent: 'flex-end' }}>
          <Dialog.Close asChild>
            <button className="Button green">Save changes</button>
          </Dialog.Close>
        </div>
        <Dialog.Close asChild>
          <button className="IconButton" aria-label="Close">
            <Cross2Icon />
          </button>
        </Dialog.Close>
      </Dialog.Content>
    </Dialog.Portal>
  </Dialog.Root>
);

export default DialogDemo;

Examples

Close after asynchronous form submission

Use the controlled props to programmatically close the Dialog after an async operation has completed.

import React from 'react';
import * as Dialog from '@radix-ui/react-dialog';

const wait = () => new Promise((resolve) => setTimeout(resolve, 1000));

export default () => {
  const [open, setOpen] = React.useState(false);

  return (
    <Dialog.Root open={open} onOpenChange={setOpen}>
      <Dialog.Trigger>Open</Dialog.Trigger>
      <Dialog.Portal>
        <Dialog.Overlay />
        <Dialog.Content>
          <form
            onSubmit={(event) => {
              wait().then(() => setOpen(false));
              event.preventDefault();
            }}
          >
            {/** some inputs */}
            <button type="submit">Submit</button>
          </form>
        </Dialog.Content>
      </Dialog.Portal>
    </Dialog.Root>
  );
};

Scrollable overlay

Move the content inside the overlay to render a dialog with overflow.

// index.jsx
import * as Dialog from '@radix-ui/react-dialog';
import './styles.css';

export default () => {
  return (
    <Dialog.Root>
      <Dialog.Trigger />
      <Dialog.Portal>
        <Dialog.Overlay className="DialogOverlay">
          <Dialog.Content className="DialogContent">...</Dialog.Content>
        </Dialog.Overlay>
      </Dialog.Portal>
    </Dialog.Root>
  );
};

/* styles.css */
.DialogOverlay {
  background: rgba(0 0 0 / 0.5);
  position: fixed;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  display: grid;
  place-items: center;
  overflow-y: auto;
}

.DialogContent {
  min-width: 300px;
  background: white;
  padding: 30px;
  border-radius: 4px;
}

Custom portal container

Customise the element that your dialog portals into.

import React from 'react';
import * as Dialog from '@radix-ui/react-dialog';

export default () => {
  const [container, setContainer] = React.useState(null);
  return (
    <div>
      <Dialog.Root>
        <Dialog.Trigger />
        <Dialog.Portal container={container}>
          <Dialog.Overlay />
          <Dialog.Content>...</Dialog.Content>
        </Dialog.Portal>
      </Dialog.Root>

      <div ref={setContainer} />
    </div>
  );
};

Accessibility

Adheres to the Dialog WAI-ARIA design pattern.

Keyboard Interactions

Key	Description
`Space`	Opens/closes the dialog.
`Enter`	Opens/closes the dialog.
`Tab`	Moves focus to the next focusable element.
`Shift + Tab`	Moves focus to the previous focusable element.
`Esc`	Closes the dialog and moves focus to `Dialog.Trigger`.

Custom APIs

Create your own API by abstracting the primitive parts into your own component.

Abstract the overlay and the close button

This example abstracts the Dialog.Overlay and Dialog.Close parts.

Usage

import { Dialog, DialogTrigger, DialogContent } from './your-dialog';

export default () => (
  <Dialog>
    <DialogTrigger>Dialog trigger</DialogTrigger>
    <DialogContent>Dialog Content</DialogContent>
  </Dialog>
);

Implementation

// your-dialog.jsx
import React from 'react';
import * as DialogPrimitive from '@radix-ui/react-dialog';
import { Cross1Icon } from '@radix-ui/react-icons';

export const DialogContent = React.forwardRef(
  ({ children, ...props }, forwardedRef) => (
    <DialogPrimitive.Portal>
      <DialogPrimitive.Overlay />
      <DialogPrimitive.Content {...props} ref={forwardedRef}>
        {children}
        <DialogPrimitive.Close aria-label="Close">
          <Cross1Icon />
        </DialogPrimitive.Close>
      </DialogPrimitive.Content>
    </DialogPrimitive.Portal>
  )
);

export const Dialog = DialogPrimitive.Root;
export const DialogTrigger = DialogPrimitive.Trigger;
