import { RadialBarChart } from '@mantine/charts';

const data = [
  { name: '18-24', value: 31.47, color: 'blue.7' },
  { name: '25-29', value: 26.69, color: 'orange.6' },
  { name: '30-34', value: 15.69, color: 'yellow.7' },
  { name: '35-39', value: 8.22, color: 'cyan.6' },
  { name: '40-49', value: 8.63, color: 'green' },
  { name: '50+', value: 2.63, color: 'pink' },
  { name: 'unknown', value: 6.67, color: 'gray' },
];

  return <RadialBarChart data={data} dataKey="value" h={280} withLabels />;
}

FunnelChart component

New FunnelChart component:

import { FunnelChart } from '@mantine/charts';

  { name: 'Japan', value: 100, color: 'teal.6' },
  { name: 'Other', value: 200, color: 'gray.6' },
];

function Demo() {
  return <FunnelChart data={data} />;
}

Modal.Stack and Drawer.Stack components

New Modal.Stack and Drawer.Stack components simplify usage of multiple modals/drawers at the same time.

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

useModalsStack/useDrawersStack hooks

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 ModalStackReturnType<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>
    </>
  );
}

Restrict Slider selection to marks

Slider component now supports restrictToMarks prop that restricts slider value to marks only.
Note that in this case step prop is ignored:

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

function Demo() {
  return (
    <Slider
      restrictToMarks
      defaultValue={25}
      marks={Array.from({ length: 5 }).map((_, index) => ({ value: index * 25 }))}
    />
  );
}

BarChart SVG pattern fill

BarChart now can be used with SVG pattern fill:

import { BarChart } from '@mantine/charts';
import { data } from './data';

function Demo() {
  return (
    <BarChart
      h={300}
      data={mixedStackData}
      dataKey="month"
      series={[
        { name: 'Smartphones', color: 'url(#crosshatch)', stackId: 'a' },
        { name: 'Laptops', color: 'blue.6', stackId: 'b' },
        { name: 'Tablets', color: 'url(#diagonalStripes)', stackId: 'b' },
      ]}
    >
      <defs>
        <pattern
          id="diagonalStripes"
          patternUnits="userSpaceOnUse"
          width={6}
          height={8}
          patternTransform="rotate(45)"
        >
          <rect
            width="2"
            height="8"
            transform="translate(0,0)"
            fill="color-mix(in lch, var(--mantine-color-teal-6) 70%, rgba(0,0,0,0))"
          />
        </pattern>

        <pattern id="crosshatch" patternUnits="userSpaceOnUse" width={8} height={8}>
          <path
            d="M 0 0 L 8 0 L 8 8 L 0 8 Z"
            fill="none"
            stroke="color-mix(in lch, var(--mantine-color-indigo-6) 70%, rgba(0,0,0,0))"
            strokeWidth="1"
          />
          <path
            d="M 0 0 L 8 8"
            stroke="color-mix(in lch, var(--mantine-color-indigo-6) 70%, rgba(0,0,0,0))"
            strokeWidth="1"
          />
          <path
            d="M 8 0 L 0 8"
            stroke="color-mix(in lch, var(--mantine-color-indigo-6) 70%, rgba(0,0,0,0))"
            strokeWidth="1"
          />
        </pattern>
      </defs>
    </BarChart>
  );
}

Container queries support in Grid

You can now use container queries
in Grid component. With container queries, all responsive values
are adjusted based on the container width, not the viewport width.

Example of using container queries. To see how the grid changes, resize the root element
of the demo with the resize handle located at the bottom right corner of the demo:

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

function Demo() {
  return (
    // Wrapper div is added for demonstration purposes only,
    // it is not required in real projects
    <div style={{ resize: 'horizontal', overflow: 'hidden', maxWidth: '100%' }}>
      <Grid
        type="container"
        breakpoints={{ xs: '100px', sm: '200px', md: '300px', lg: '400px', xl: '500px' }}
      >
        <Col span={{ base: 12, md: 6, lg: 3 }}>1</Col>
        <Col span={{ base: 12, md: 6, lg: 3 }}>2</Col>
        <Col span={{ base: 12, md: 6, lg: 3 }}>3</Col>
        <Col span={{ base: 12, md: 6, lg: 3 }}>4</Col>
      </Grid>
    </div>
  );
}

CompositeChart component

New CompositeChart component allows using Line, Area and Bar charts together in a single chart:

import { CompositeChart } from '@mantine/charts';
import { data } from './data';

function Demo() {
  return (
    <CompositeChart
      h={300}
      data={data}
      dataKey="date"
      unit="$"
      maxBarWidth={30}
      series={[
        { name: 'Tomatoes', color: 'rgba(18, 120, 255, 0.2)', type: 'bar' },
        { name: 'Apples', color: 'red.8', type: 'line' },
        { name: 'Oranges', color: 'yellow.8', type: 'area' },
      ]}
    />
  );
}

Points labels

LineChart and AreaChart now support withPointLabels prop to display labels on data points:

import { LineChart } from '@mantine/charts';
import { data } from './data';

function Demo() {
  return (
    <LineChart
      h={300}
      data={data}
      dataKey="date"
      withLegend
      withPointLabels
      series={[
        { name: 'Apples', color: 'indigo.6' },
        { name: 'Oranges', color: 'blue.6' },
      ]}
    />
  );
}

ScatterChart also supports point labels, but also allows to control which axis should display labels with pointLabels prop:

import { ScatterChart } from '@mantine/charts';
import { data } from './data';

function Demo() {
  return (
    <ScatterChart
      h={350}
      data={data}
      dataKey={{ x: 'age', y: 'BMI' }}
      xAxisLabel="Age"
      yAxisLabel="BMI"
      pointLabels="x"
    />
  );
}

BarChart: Mixed stacks

You can now control how BarChart series are stacked by setting stackId property in series object:

import { BarChart } from '@mantine/charts';
import { data } from './data';

function Demo() {
  return (
    <BarChart
      h={300}
      data={data}
      dataKey="month"
      series={[
        { name: 'Smartphones', color: 'violet.6', stackId: 'a' },
        { name: 'Laptops', color: 'blue.6', stackId: 'b' },
        { name: 'Tablets', color: 'teal.6', stackId: 'b' },
      ]}
    />
  );
}

BarChart: Minimum bar size

BarChart now supports minBarSize prop to set the minimum size of the bar in px:

import { BarChart } from '@mantine/charts';
import { data } from './data';

function Demo() {
  return (
    <BarChart
      h={300}
      data={data}
      dataKey="month"
      withLegend
      series={[
        { name: 'Smartphones', color: 'violet.6' },
        { name: 'Laptops', color: 'blue.6' },
        { name: 'Tablets', color: 'teal.6' },
      ]}
    />
  );
}

Notifications at any position

It is now possible to display notifications at any position on the screen
with @mantine/notifications package:

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

const positions = [
  'top-left',
  'top-right',
  'bottom-left',
  'bottom-right',
  'top-center',
  'bottom-center',
] as const;

function Demo() {
  const buttons = positions.map((position) => (
    <Button
      key={position}
      onClick={() =>
        notifications.show({
          title: `Notification at ${position}`,
          message: `Notification at ${position} message`,
          position,
        })
      }
    >
      {position}
    </Button>
  ));

  return <Group>{buttons}</Group>;
}

Subscribe to notifications state

You can now subscribe to notifications state changes with useNotifications hook:

function Demo() {
  const [counter, { increment }] = useCounter();
  const notificationsStore = useNotifications();

  const showNotification = () => {
    notifications.show({
      title: `Notification ${counter}`,
      message: 'Most notifications are added to queue',
    });

    increment();
  };

  return (
    <>
      <Button onClick={showNotification} mb="md">
        Show notification
      </Button>

      <Text>Notifications state</Text>
      <Code block>{JSON.stringify(notificationsStore.notifications, null, 2)}</Code>

      <Text mt="md">Notifications queue</Text>
      <Code block>{JSON.stringify(notificationsStore.queue, null, 2)}</Code>
    </>
  );
}

SemiCircleProgress component

New SemiCircleProgress component:

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

function Demo() {
  return (
    <SemiCircleProgress
      fillDirection="left-to-right"
      orientation="up"
      filledSegmentColor="blue"
      size={200}
      thickness={12}
      value={40}
      label="Label"
    />
  );
}

Tree checked state

Tree component now supports checked state:

import { IconChevronDown } from '@tabler/icons-react';
import { Checkbox, Group, RenderTreeNodePayload, Tree } from '@mantine/core';
import { data } from './data';

const renderTreeNode = ({
  node,
  expanded,
  hasChildren,
  elementProps,
  tree,
}: RenderTreeNodePayload) => {
  const checked = tree.isNodeChecked(node.value);
  const indeterminate = tree.isNodeIndeterminate(node.value);

  return (
    <Group gap="xs" {...elementProps}>
      <Checkbox.Indicator
        checked={checked}
        indeterminate={indeterminate}
        onClick={() => (!checked ? tree.checkNode(node.value) : tree.uncheckNode(node.value))}
      />

      <Group gap={5} onClick={() => tree.toggleExpanded(node.value)}>
        <span>{node.label}</span>

        {hasChildren && (
          <IconChevronDown
            size={14}
            style={{ transform: expanded ? 'rotate(180deg)' : 'rotate(0deg)' }}
          />
        )}
      </Group>
    </Group>
  );
};

function Demo() {
  return <Tree data={data} levelOffset={23} expandOnClick={false} renderNode={renderTreeNode} />;
}
