Setup ModalsProvider

Wrap your app with ModalsProvider component:

import { MantineProvider } from '@mantine/core';
import { ModalsProvider } from '@mantine/modals';

function Demo() {
  return (
    <MantineProvider>
      <ModalsProvider>
        <App />
      </ModalsProvider>
    </MantineProvider>
  );
}

@mantine/modals package includes special modal that can be used for confirmations. Component includes confirm and cancel buttons and supports children to display additional information about action. Use openConfirmModal function to open a confirm modal:

import { Button, Text } from '@mantine/core';
import { modals } from '@mantine/modals';

function Demo() {
  const openModal = () => modals.openConfirmModal({
    title: 'Please confirm your action',
    children: (
      <Text size="sm">
        This action is so important that you are required to confirm it with a modal. Please click
        one of these buttons to proceed.
      </Text>
    ),
    labels: { confirm: 'Confirm', cancel: 'Cancel' },
    onCancel: () => console.log('Cancel'),
    onConfirm: () => console.log('Confirmed'),
  });

  return <Button onClick={openModal}>Open confirm modal</Button>;
}

openConfirmModal function accepts one argument with following properties:

modalId – modal id, defaults to random id, can be used to close modal programmatically
children – additional modal content displayed before actions
onCancel – called when cancel button is clicked
onConfirm – called when confirm button is clicked
closeOnConfirm – should modal be closed when confirm button is clicked, defaults to true
closeOnCancel – should modal be closed when cancel button is clicked, defaults to true
cancelProps – cancel button props
confirmProps – confirm button props
groupProps – buttons Group props
labels – cancel and confirm buttons labels, can be defined on ModalsProvider

Using this properties you can customize confirm modal to match current context requirements:

import { Button, Text } from '@mantine/core';
import { modals } from '@mantine/modals';

function Demo() {
  const openDeleteModal = () =>
    modals.openConfirmModal({
      title: 'Delete your profile',
      centered: true,
      children: (
        <Text size="sm">
          Are you sure you want to delete your profile? This action is destructive and you will have
          to contact support to restore your data.
        </Text>
      ),
      labels: { confirm: 'Delete account', cancel: "No don't delete it" },
      confirmProps: { color: 'red' },
      onCancel: () => console.log('Cancel'),
      onConfirm: () => console.log('Confirmed'),
    });

  return <Button onClick={openDeleteModal} color="red">Delete account</Button>;
}

To setup shared labels for confirm modals set labels on ModalsProvider:

import { ModalsProvider } from '@mantine/modals';

function Demo() {
  return (
    <ModalsProvider labels={{ confirm: 'Submit', cancel: 'Cancel' }}>
      <App />
    </ModalsProvider>
  );
}

Context modals

You can define any amount of modals in ModalsProvider context:

import { ContextModalProps, ModalsProvider } from '@mantine/modals';
import { Text, Button } from '@mantine/core';

const TestModal = ({ context, id, innerProps }: ContextModalProps<{ modalBody: string }>) => (
  <>
    <Text size="sm">{innerProps.modalBody}</Text>
    <Button fullWidth mt="md" onClick={() => context.closeModal(id)}>
      Close modal
    </Button>
  </>
);

function Demo() {
  return (
    <ModalsProvider modals={{ demonstration: TestModal /* ...other modals */ }}>
      <App />
    </ModalsProvider>
  );
}

And then open one of these modals with modals.openContextModal function. modals.openContextModal function accepts 2 arguments: modal key (should match one defined on ModalsProvider) and modal props:

import { Button } from '@mantine/core';
import { modals } from '@mantine/modals';

function Demo() {
  return (
    <Button
      onClick={() =>
        modals.openContextModal({
          modal: 'demonstration',
          title: 'Test modal from context',
          innerProps: {
            modalBody:
              'This modal was defined in ModalsProvider, you can open it anywhere in you app with useModals hook',
          },
        })
      }
    >
      Open demonstration context modal
    </Button>
  );
}

Typesafe context modals

By default innerProps and modal are not typesafe. You can add typesafety with a Typescript module declaration.

const TestModal = ({ context, id, innerProps }: ContextModalProps<{ modalBody: string }>) => (
  <>
    <Text size="sm">{innerProps.modalBody}</Text>
    <Button fullWidth mt="md" onClick={() => context.closeModal(id)}>
      Close modal
    </Button>
  </>
);
const modals = {
  demonstration: TestModal,
  /* ...other modals */
};
declare module '@mantine/modals' {
  export interface MantineModalsOverride {
    modals: typeof modals;
  }
}
function Demo() {
  return (
    <ModalsProvider modals={modals}>
      <App />
    </ModalsProvider>
  );
}

Typesafe context modals will force you to use the correct types for openContextModal:

import { openContextModal, closeModal } from '@mantine/modals';
openContextModal({
  modal: 'demonstration',
  title: 'Test modal from context',
  innerProps: {
    modalBody:
      'This modal was defined in ModalsProvider, you can open it anywhere in you app with useModals hook',
  },
});
closeModal('demonstration');

Content modals

With modals.open function you can open a modal with any content:

import { TextInput, Button } from '@mantine/core';
import { modals } from '@mantine/modals';

function Demo() {
  return (
    <Button
      onClick={() => {
        modals.open({
          title: 'Subscribe to newsletter',
          children: (
            <>
              <TextInput label="Your email" placeholder="Your email" data-autofocus />
              <Button fullWidth onClick={() => modals.closeAll()} mt="md">
                Submit
              </Button>
            </>
          ),
        });
      }}
    >
      Open content modal
    </Button>
  );
}

Multiple opened modals

You can open multiple layers of modals. Every opened modal is added as first element in modals queue. To close all opened modals call modals.closeAll() function:

import { Button, Text } from '@mantine/core';
import { modals } from '@mantine/modals';

function Demo() {
  return (
    <Button
      onClick={() =>
        modals.openConfirmModal({
          title: 'Please confirm your action',
          closeOnConfirm: false,
          labels: { confirm: 'Next modal', cancel: 'Close modal' },
          children: (
            <Text size="sm">
              This action is so important that you are required to confirm it with a modal. Please
              click one of these buttons to proceed.
            </Text>
          ),
          onConfirm: () =>
            modals.openConfirmModal({
              title: 'This is modal at second layer',
              labels: { confirm: 'Close modal', cancel: 'Back' },
              closeOnConfirm: false,
              children: (
                <Text size="sm">
                  When this modal is closed modals state will revert to first modal
                </Text>
              ),
              onConfirm: modals.closeAll,
            }),
        })
      }
    >
      Open multiple steps modal
    </Button>
  );
}

Dynamic Content and the modals manager

Note that when using the Modals manager, dynamic content is not supported. Once modal is opened, a snapshot is saved into internal state and cannot be updated.

If you intend to have dynamic content in modals, either:

Use internal component state, or
Use the modal component instead of modals manager
