withProps function

All Mantine components now have withProps static function that can be used to add default props to the component:

import { IMaskInput } from 'react-imask';
import { Button, InputBase } from '@mantine/core';

const LinkButton = Button.withProps({
  component: 'a',
  target: '_blank',
  rel: 'noreferrer',
  variant: 'subtle',
});

const PhoneInput = InputBase.withProps({
  mask: '+7 (000) 000-0000',
  component: IMaskInput,
  label: 'Your phone number',
  placeholder: 'Your phone number',
});

function Demo() {
  return (
    <>
      {/* You can pass additional props to components created with `withProps` */}
      <LinkButton href="https://mantine.dev">Mantine website</LinkButton>

      {/* Component props override default props defined in `withProps` */}
      <PhoneInput placeholder="Personal phone" />
    </>
  );
}

Avatar initials

Avatar component now supports displaying initials with auto generated color based on the given name value. To display initials instead of the default placeholder, set name prop to the name of the person, for example, name="John Doe". If the name is set, you can use color="initials" to generate color based on the name:

import { Avatar, Group } from '@mantine/core';

const names = [
  'John Doe',
  'Jane Mol',
  'Alex Lump',
  'Sarah Condor',
  'Mike Johnson',
  'Kate Kok',
  'Tom Smith',
];

function Demo() {
  const avatars = names.map((name) => <Avatar key={name} name={name} color="initials" />);
  return <Group>{avatars}</Group>;
}

BubbleChart component

      range={[16, 225]}

      dataKey={{ x: 'hour', y: 'index', z: 'value' }}
    />
  );
}

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

function Demo() {
  return (
    <BarChart
      h={300}
      data={data}
      dataKey="item"
      type="waterfall"
      series={[{ name: 'Effective tax rate in %', color: 'blue' }]}
      withLegend
    />
  );
}

  return (
    <LineChart

      data={data}
      series={[{ name: 'temperature', label: 'Avg. Temperature' }]}
      dataKey="date"
      type="gradient"
      gradientStops={[
        { offset: 0, color: 'red.6' },
        { offset: 20, color: 'orange.6' },
        { offset: 40, color: 'yellow.5' },
        { offset: 70, color: 'lime.5' },

      valueFormatter={(value) => `${value}°C`}
    />
  );
}

Right Y axis

LineChart, BarChart and AreaChart components now support rightYAxis prop which renders additional Y axis on the right side of the chart:

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

function Demo() {
  return (
    <LineChart
      h={300}
      data={data}
      dataKey="name"
      withRightYAxis
      yAxisLabel="uv"
      rightYAxisLabel="pv"
      series={[
        { name: 'uv', color: 'pink.6' },

      ]}
    />
  );
}

TagsInput acceptValueOnBlur

TagsInput component behavior has been changed. Now By default, if the user types in a value and blurs the input, the value is added to the list. You can change this behavior by setting acceptValueOnBlur to false. In this case, the value is added only when the user presses Enter or clicks on a suggestion.

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

function Demo() {
  return (
    <>
      <TagsInput
        label="Value IS accepted on blur"
        placeholder="Enter text, then blur the field"
        data={['React', 'Angular', 'Svelte']}
        acceptValueOnBlur
      />
      <TagsInput
        label="Value IS NOT accepted on blur"
        placeholder="Enter text, then blur the field"
        data={['React', 'Angular', 'Svelte']}
        acceptValueOnBlur={false}
        mt="md"
      />
    </>
  );
}

Transition delay

Transition component now supports enterDelay and exitDelay props to delay transition start:

import { useState } from 'react';
import { Button, Flex, Paper, Transition } from '@mantine/core';

export function Demo() {
  const [opened, setOpened] = useState(false);

  return (
    <Flex maw={200} pos="relative" justify="center" m="auto">
      <Button onClick={() => setOpened(true)}>Open dropdown</Button>

      <Transition mounted={opened} transition="pop" enterDelay={500} exitDelay={300}>
        {(transitionStyle) => (
          <Paper
            shadow="md"
            p="xl"
            h={120}
            pos="absolute"
            inset={0}
            bottom="auto"
            onClick={() => setOpened(false)}
            style={{ ...transitionStyle, zIndex: 1 }}
          >
            Click to close
          </Paper>
