Usage

import { useDisclosure } from '@mantine/hooks';
import { Modal, Button } from '@mantine/core';

function Demo() {
  const [opened, { open, close }] = useDisclosure(false);

  return (
    <>
      <Modal opened={opened} onClose={close} title="Authentication">
        {/* Modal content */}
      </Modal>

      <Button variant="default" onClick={open}>
        Open modal
      </Button>
    </>
  );
}

Center modal vertically

import { useDisclosure } from '@mantine/hooks';
import { Modal, Button } from '@mantine/core';

function Demo() {
  const [opened, { open, close }] = useDisclosure(false);

  return (
    <>
      <Modal opened={opened} onClose={close} title="Authentication" centered>
        {/* Modal content */}
      </Modal>

      <Button variant="default" onClick={open}>
        Open centered Modal
      </Button>
    </>
  );
}

Remove header

To remove header set withCloseButton={false}:

import { useDisclosure } from '@mantine/hooks';
import { Modal, Button } from '@mantine/core';

function Demo() {
  const [opened, { open, close }] = useDisclosure(false);

  return (
    <>
      <Modal opened={opened} onClose={close} withCloseButton={false}>
        Modal without header, press escape or click on overlay to close
      </Modal>

      <Button variant="default" onClick={open}>
        Open modal
      </Button>
    </>
  );
}

Change size

You can change modal width by setting size prop to predefined size or any valid width, for example, 55% or 50rem. Modal width cannot exceed 100vw.

Size auto

Modal with size="auto" will have width to fit its content:

import { useDisclosure, useCounter } from '@mantine/hooks';
import { Modal, Button, Group, Text, Badge } from '@mantine/core';

function Demo() {
  const [opened, { close, open }] = useDisclosure(false);
  const [count, { increment, decrement }] = useCounter(3, { min: 0 });

  const badges = Array(count)
    .fill(0)
    .map((_, index) => <Badge key={index}>Badge {index}</Badge>);

  return (
    <>
      <Modal opened={opened} onClose={close} size="auto" title="Modal size auto">
        <Text>Modal with size auto will fits its content</Text>

        <Group wrap="nowrap" mt="md">
          {badges}
        </Group>

        <Group mt="xl">
          <Button onClick={increment}>Add badge</Button>
          <Button onClick={decrement}>Remove badge</Button>
        </Group>
      </Modal>

      <Button variant="default" onClick={open}>
        Open modal
      </Button>
    </>
  );
}

Fullscreen

Fullscreen modal will take the entire screen, it is usually better to change transition to fade when fullScreen prop is set:

import { useDisclosure } from '@mantine/hooks';
import { Modal, Button } from '@mantine/core';

function Demo() {
  const [opened, { open, close }] = useDisclosure(false);

  return (
    <>
      <Modal
        opened={opened}
        onClose={close}
        title="This is a fullscreen modal"
        fullScreen
        radius={0}
        transitionProps={{ transition: 'fade', duration: 200 }}
      >
        {/* Modal content */}
      </Modal>

      <Button variant="default" onClick={open}>
        Open modal
      </Button>
    </>
  );
}

To switch Modal to fullscreen on devices with small screens only use use-media-query hook. size prop is ignored if fullScreen prop is set:

import { useDisclosure, useMediaQuery } from '@mantine/hooks';
import { Modal, Button } from '@mantine/core';

function Demo() {
  const [opened, { open, close }] = useDisclosure(false);
  const isMobile = useMediaQuery('(max-width: 50em)');

  return (
    <>
      <Modal
        opened={opened}
        onClose={close}
        title="This is a fullscreen modal"
        fullScreen={isMobile}
        transitionProps={{ transition: 'fade', duration: 200 }}
      >
        The Modal will be full screen only on mobile
      </Modal>

      <Button variant="default" onClick={open}>
        Open modal
      </Button>
    </>
  );
}

Customize overlay

Modal uses Overlay component, you can set any props that Overlay supports with overlayProps:

import { useDisclosure } from '@mantine/hooks';
import { Modal, Button } from '@mantine/core';

function Demo() {
  const [opened, { open, close }] = useDisclosure(false);

  return (
    <>
      <Modal
        opened={opened}
        onClose={close}
        title="Authentication"
        overlayProps={{
          backgroundOpacity: 0.55,
          blur: 3,
        }}
      >
        {/* Modal content */}
      </Modal>

      <Button variant="default" onClick={open}>
        Open modal
      </Button>
    </>
  );
}

Modal with scroll

import { useDisclosure } from '@mantine/hooks';
import { Modal, Button } from '@mantine/core';

function Demo() {
  const [opened, { open, close }] = useDisclosure(false);

  const content = Array(100)
    .fill(0)
    .map((_, index) => <p key={index}>Modal with scroll</p>);

  return (
    <>
      <Modal opened={opened} onClose={close} title="Header is sticky">
        {content}
      </Modal>

      <Button variant="default" onClick={open}>
        Open modal
      </Button>
    </>
  );
}

Usage with ScrollArea

import { useDisclosure } from '@mantine/hooks';
import { Modal, Button, ScrollArea } from '@mantine/core';

function Demo() {
  const [opened, { open, close }] = useDisclosure(false);

  const content = Array(100)
    .fill(0)
    .map((_, index) => <p key={index}>Modal with scroll</p>);

  return (
    <>
      <Modal
        opened={opened}
        onClose={close}
        title="Header is sticky"
        scrollAreaComponent={ScrollArea.Autosize}
      >
        {content}
      </Modal>

      <Button variant="default" onClick={open}>
        Open modal
      </Button>
    </>
  );
}

Change offsets

Use xOffset/yOffset to configure horizontal/vertical content offsets:

import { useDisclosure } from '@mantine/hooks';
import { Modal, Button } from '@mantine/core';

function Demo() {
  const [opened, { open, close }] = useDisclosure(false);

  return (
    <>
      <Modal opened={opened} onClose={close} title="Authentication" yOffset="1vh" xOffset={0}>
        {/* Modal content */}
      </Modal>

      <Button variant="default" onClick={open}>
        Open modal
      </Button>
    </>
  );
}

Change transitions

Modal is built with Transition component. Use transitionProps prop to customize any Transition properties:

import { useState } from 'react';
import { Modal, Group, Button } from '@mantine/core';

function Demo() {
  const [noTransitionOpened, setNoTransitionOpened] = useState(false);
  const [slowTransitionOpened, setSlowTransitionOpened] = useState(false);

  return (
    <>
      <Modal
        opened={slowTransitionOpened}
        onClose={() => setSlowTransitionOpened(false)}
        title="Please consider this"
        transitionProps={{ transition: 'rotate-left' }}
      >
        rotate-left transition
      </Modal>

      <Modal
        opened={noTransitionOpened}
        onClose={() => setNoTransitionOpened(false)}
        title="Please consider this"
        transitionProps={{ transition: 'fade', duration: 600, timingFunction: 'linear' }}
      >
        fade transition 600ms linear transition
      </Modal>

      <Group justify="center">
        <Button onClick={() => setSlowTransitionOpened(true)} variant="default">
          Rotate left transition
        </Button>
        <Button onClick={() => setNoTransitionOpened(true)} variant="default">
          Fade transition
        </Button>
      </Group>
    </>
  );
}

onExitTransitionEnd and onEnterTransitionEnd

onExitTransitionEnd and onEnterTransitionEnd props can be used to run code after exit/enter transition is finished. For example, this is useful when you want to clear data after modal is closed:

import { useState } from 'react';
import { Button, Group, Modal } from '@mantine/core';
import { useDisclosure } from '@mantine/hooks';

function Demo() {
  const [firstOpened, firstHandlers] = useDisclosure(false);
  const [secondOpened, secondHandlers] = useDisclosure(false);
  const [modalData, setModalData] = useState({
    title: '',
    message: '',
  });

  return (
    <>
      <Modal
        opened={firstOpened}
        onClose={() => {
          firstHandlers.close();
          setModalData({ title: '', message: '' });
        }}
        title={modalData.title}
      >
        {modalData.message}
      </Modal>
      <Modal
        opened={secondOpened}
        onClose={secondHandlers.close}
        onExitTransitionEnd={() => setModalData({ title: '', message: '' })}
        title={modalData.title}
      >
        {modalData.message}
      </Modal>

      <Group>
        <Button
          onClick={() => {
            firstHandlers.open();
            setModalData({ title: 'Edit your profile', message: 'Imagine a form here' });
          }}
        >
          Clear data in onClose
        </Button>

        <Button
          onClick={() => {
            secondHandlers.open();
            setModalData({ title: 'Edit your profile', message: 'Imagine a form here' });
          }}
        >
          Clear data in onExitTransitionEnd
        </Button>
      </Group>
    </>
  );
}

Initial focus

Modal uses FocusTrap to trap focus. Add data-autofocus attribute to the element that should receive initial focus.

import { useDisclosure } from '@mantine/hooks';
import { Modal, Button, TextInput } from '@mantine/core';

function Demo() {
  const [opened, { open, close }] = useDisclosure(false);

  return (
    <>
      <Modal opened={opened} onClose={close} title="Focus demo">
        <TextInput label="First input" placeholder="First input" />
        <TextInput
          data-autofocus
          label="Input with initial focus"
          placeholder="It has data-autofocus attribute"
          mt="md"
        />
      </Modal>

      <Button variant="default" onClick={open}>
        Open modal
      </Button>
    </>
  );
}

If you do not want to focus any elements when the modal is opened, use FocusTrap.InitialFocus component to create a visually hidden element that will receive initial focus:

import { useDisclosure } from '@mantine/hooks';
import { Modal, Button, TextInput, FocusTrap } from '@mantine/core';

function Demo() {
  const [opened, { open, close }] = useDisclosure(false);

  return (
    <>
      <Modal opened={opened} onClose={close} title="Focus demo">
        <FocusTrap.InitialFocus />
        <TextInput label="First input" placeholder="First input" />
        <TextInput
          data-autofocus
          label="Input with initial focus"
          placeholder="It has data-autofocus attribute"
          mt="md"
        />
      </Modal>

      <Button variant="default" onClick={open}>
        Open modal
      </Button>
    </>
  );
}

If you do not add data-autofocus attribute and do not use FocusTrap.InitialFocus, modal will focus the first focusable element inside it which is usually the close button.

Control behavior

The following props can be used to control Modal behavior. In most cases, it is not recommended to turn these features off – it will make the component less accessible.

trapFocus – determines whether focus should be trapped inside modal
closeOnEscape – determines whether the modal should be closed when Escape key is pressed
closeOnClickOutside – determines whether the modal should be closed when user clicks on the overlay
returnFocus – determines whether focus should be returned to the element that was focused before the modal was opened

react-remove-scroll settings

Modal uses react-remove-scroll package to lock scroll. You can pass props down to the RemoveScroll component with removeScrollProps:

import { Modal } from '@mantine/core';

function Demo() {
  return (
    <Modal
      removeScrollProps={{ allowPinchZoom: true }}
      opened
      onClose={() => {}}
    />
  );
}

Change close icon

Use closeButtonProps to customize close button:

import { IconXboxX } from '@tabler/icons-react';
import { useDisclosure } from '@mantine/hooks';
import { Modal, Button } from '@mantine/core';

function Demo() {
  const [opened, { open, close }] = useDisclosure(false);

  return (
    <>
      <Modal
        opened={opened}
        onClose={close}
        title="Authentication"
        closeButtonProps={{
          icon: <IconXboxX size={20} stroke={1.5} />,
        }}
      >
        {/* Modal content */}
      </Modal>

      <Button variant="default" onClick={open}>
        Open modal
      </Button>
    </>
  );
}

Compound components

You can use the following compound components to have full control over the Modal rendering:

Modal.Root – context provider
Modal.Overlay – render Overlay
Modal.Content – main modal element, should include all modal content
Modal.Header – sticky header, usually contains Modal.Title and Modal.CloseButton
Modal.Title – h2 element, aria-labelledby of Modal.Content is pointing to this element, usually is rendered inside Modal.Header
Modal.CloseButton – close button, usually rendered inside Modal.Header
Modal.Body – a place for main content, aria-describedby of Modal.Content is pointing to this element

import { useDisclosure } from '@mantine/hooks';
import { Modal, Button } from '@mantine/core';

function Demo() {
  const [opened, { open, close }] = useDisclosure(false);

  return (
    <>
      <Modal.Root opened={opened} onClose={close}>
        <Modal.Overlay />
        <Modal.Content>
          <Modal.Header>
            <Modal.Title>Modal title</Modal.Title>
            <Modal.CloseButton />
          </Modal.Header>
          <Modal.Body>Modal content</Modal.Body>
        </Modal.Content>
      </Modal.Root>

      <Button variant="default" onClick={open}>
        Open modal
      </Button>
    </>
  );
}

Use Modal.Stack component to render multiple modals at the same time. Modal.Stack keeps track of opened modals, manages z-index values, focus trapping and closeOnEscape behavior. Modal.Stack is designed to be used with useModalsStack hook.

Differences from using multiple Modal components:

Modal.Stack manages z-index values – modals that are opened later will always have higher z-index value disregarding their order in the DOM
Modal.Stack disables focus trap and Escape key handling for all modals except the one that is currently opened
Modals that are not currently opened are present in the DOM but are hidden with opacity: 0 and pointer-events: none
Only one overlay is rendered at a time

import { Button, Group, Modal, useModalsStack } from '@mantine/core';

function Demo() {
  const stack = useModalsStack(['delete-page', 'confirm-action', 'really-confirm-action']);

  return (
    <>
      <Modal.Stack>
        <Modal {...stack.register('delete-page')} title="Delete this page?">
          Are you sure you want to delete this page? This action cannot be undone.
          <Group mt="lg" justify="flex-end">
            <Button onClick={stack.closeAll} variant="default">
              Cancel
            </Button>
            <Button onClick={() => stack.open('confirm-action')} color="red">
              Delete
            </Button>
          </Group>
        </Modal>

        <Modal {...stack.register('confirm-action')} title="Confirm action">
          Are you sure you want to perform this action? This action cannot be undone. If you are
          sure, press confirm button below.
          <Group mt="lg" justify="flex-end">
            <Button onClick={stack.closeAll} variant="default">
              Cancel
            </Button>
            <Button onClick={() => stack.open('really-confirm-action')} color="red">
              Confirm
            </Button>
          </Group>
        </Modal>

        <Modal {...stack.register('really-confirm-action')} title="Really confirm action">
          Jokes aside. You have confirmed this action. This is your last chance to cancel it. After
          you press confirm button below, action will be performed and cannot be undone. For real
          this time. Are you sure you want to proceed?
          <Group mt="lg" justify="flex-end">
            <Button onClick={stack.closeAll} variant="default">
              Cancel
            </Button>
            <Button onClick={stack.closeAll} color="red">
              Confirm
            </Button>
          </Group>
        </Modal>
      </Modal.Stack>

      <Button variant="default" onClick={() => stack.open('delete-page')}>
        Open modal
      </Button>
    </>
  );
}

Note that Modal.Stack can only be used with Modal component. Components built with Modal.Root and other compound components are not compatible with Modal.Stack.

useModalsStack hook

useModalsStack hook provides an easy way to control multiple modals at the same time. It accepts an array of unique modals ids and returns an object with the following properties:

interface UseModalsStackReturnType<T extends string> {
  // Current opened state of each modal
  state: Record<T, boolean>;

  // Opens modal with the given id
  open: (id: T) => void;

  // Closes modal with the given id
  close: (id: T) => void;

  // Toggles modal with the given id
  toggle: (id: T) => void;

  // Closes all modals within the stack
  closeAll: () => void;

  // Returns props for modal with the given id
  register: (id: T) => {
    opened: boolean;
    onClose: () => void;
    stackId: T;
  };
}

Example of using useModalsStack with Modal component:

import { Modal, useModalsStack } from '@mantine/core';

function Demo() {
  const stack = useModalsStack(['first', 'second']);

  return (
    <>
      <Modal {...stack.register('first')}>First</Modal>
      <Modal {...stack.register('second')}>Second</Modal>
      <Button onClick={() => stack.open('first')}>Open first</Button>
    </>
  );
}

Fixed elements offset

Modal component uses react-remove-scroll package to lock scroll. To properly size these elements add a className to them (documentation):

import { RemoveScroll } from '@mantine/core';

function Demo() {
  return (
    <>
      <div className={RemoveScroll.classNames.fullWidth}>
        width: 100%
      </div>
      <div className={RemoveScroll.classNames.zeroRight}>
        right: 0
      </div>
    </>
  );
}

Accessibility

Modal component follows WAI-ARIA recommendations on accessibility.

Set title props to make component accessible, will add aria-labelledby to the content element:

import { Modal } from '@mantine/core';

function Demo() {
  return <Modal title="Modal label" opened onClose={() => {}} />;
}

To set close button aria-label use closeButtonProps:

import { Modal } from '@mantine/core';

function Demo() {
  return (
    <Modal
      closeButtonProps={{ 'aria-label': 'Close modal' }}
      opened
      onClose={() => {}}
    />
  );
}
