@mantine/charts

New @mantine/charts package provides a set of components to build charts and graphs. All components are based on recharts. Currently, the package provides AreaChart, BarChart, LineChart and Sparkline components. More components will be added in the next minor releases.

AreaChart component

New AreaChart component:

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

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

LineChart component

New LineChart component:

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

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

BarChart component

New BarChart component:

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

function Demo() {
  return (
    <BarChart
      h={300}
      data={data}
      dataKey="month"
      type="stacked"
      orientation="vertical"
      yAxisProps={{ width: 80 }}
      series={[
        { name: 'Smartphones', color: 'violet.6' },
        { name: 'Laptops', color: 'blue.6' },
        { name: 'Tablets', color: 'teal.6' },
      ]}
    />
  );
}

Sparkline component

New Sparkline component:

Color
Fill opacity
Stroke width
import { Sparkline } from '@mantine/charts';

function Demo() {
  return (
    <Sparkline
      w={200}
      h={60}
      data={[10, 20, 40, 20, 40, 10, 50]}
      curveType="linear"
      color="blue"
      fillOpacity={0.6}
      strokeWidth={2}
    />
  );
}

OKLCH colors support

You can now use OKLCH colors in theme.colors. OKLCH color model has 88.18% browser support, it is supported in all modern browsers. OKLCH model provides 30% more colors than HSL model and has several other advantages.

Example of adding OKLCH color to the theme:

import { MantineProvider, createTheme, Group, Button } from '@mantine/core';

const theme = createTheme({
  colors: {
    'oklch-blue': [
      'oklch(96.27% 0.0217 238.66)',
      'oklch(92.66% 0.0429 240.01)',
      'oklch(86.02% 0.0827 241.66)',
      'oklch(78.2% 0.13 243.83)',
      'oklch(71.8% 0.1686 246.06)',
      'oklch(66.89% 0.1986 248.32)',
      'oklch(62.59% 0.2247 250.29)',
      'oklch(58.56% 0.2209 251.26)',
      'oklch(54.26% 0.2067 251.67)',
      'oklch(49.72% 0.1888 251.59)',
    ],
  }
});

function Demo() {
  return (
    <MantineProvider theme={theme}>
      <Group>
        <Button color="oklch-blue">Filled</Button>
        <Button color="oklch-blue" variant="outline">
          Outline
        </Button>
        <Button color="oklch-blue" variant="light">
          Light
        </Button>
      </Group>
    </MantineProvider>
  );
}

autoContrast

New theme.autoContrast property controls whether text color should be changed based on the given color prop in the following components:

autoContrast can be set globally on the theme level or individually for each component via autoContrast prop, except for Spotlight and @mantine/dates components, which only support global theme setting.

autoContrast: true
autoContrast: false
import { Button, Code, Group } from '@mantine/core';

function Demo() {
  return (
    <>
      <Code>autoContrast: true</Code>
      <Group mt="xs" mb="lg">
        <Button color="lime.4" autoContrast>
          Lime.4 button
        </Button>
        <Button color="blue.2" autoContrast>
          Blue.2 button
        </Button>
        <Button color="orange.3" autoContrast>
          Orange.3 button
        </Button>
      </Group>

      <Code>autoContrast: false</Code>
      <Group mt="xs">
        <Button color="lime.4">Lime.4 button</Button>
        <Button color="blue.2">Blue.2 button</Button>
        <Button color="orange.3">Orange.3 button</Button>
      </Group>
    </>
  );
}

autoContrast checks whether the given color luminosity is above or below the luminanceThreshold value and changes text color to either theme.white or theme.black accordingly:

Color
Luminance threshold
import { Button, createTheme, MantineProvider, Stack } from '@mantine/core';

const theme = createTheme({
  autoContrast: true,
  luminanceThreshold: 0.3,
});

function Wrapper(props: any) {
  const buttons = Array(10)
    .fill(0)
    .map((_, index) => (
      <Button
        key={index}
        color={`blue.${index}`}
      >
        Button
      </Button>
    ));

  return (
    <MantineProvider theme={theme}>
      <Stack>{buttons}</Stack>
    </MantineProvider>
  );
}

Color functions improvements

alpha, lighten and darken functions now support CSS variables (with color-mix) and OKLCH colors. All functions are available both in @mantine/core (.ts/.js files) and postcss-preset-mantine (.css files, requires version 1.12.0 or higher).

In .css files:

.demo-alpha {
  color: alpha(var(--mantine-color-red-4), 0.5);
  border: 1px solid alpha(#ffc, 0.2);
}

.demo-lighten-darken {
  color: lighten(var(--mantine-color-red-4), 0.5);
  border: 1px solid darken(#ffc, 0.2);
}

Will be transformed to:

.demo-alpha {
  color: color-mix(
    in srgb,
    var(--mantine-color-red-4),
    transparent 50%
  );
  border: 1px solid color-mix(in srgb, #ffc, transparent 80%);
}

.demo-lighten-darken {
  color: color-mix(in srgb, var(--mantine-color-red-4), white 50%);
  border: 1px solid color-mix(in srgb, #ffc, black 20%);
}

In .ts/.js files:

import { alpha, lighten } from '@mantine/core';

alpha('#4578FC', 0.45); // -> rgba(69, 120, 252, 0.45)
alpha('var(--mantine-color-gray-4)', 0.74);
// -> color-mix(in srgb, var(--mantine-color-gray-4), transparent 26%)

lighten('#4578FC', 0.45); // -> #a3c1ff
lighten('var(--mantine-color-gray-4)', 0.74);
// -> color-mix(in srgb, var(--mantine-color-gray-4), white 74%)

Note that alpha function is a replacement for rgba. It was renamed to have a more clear meaning, as it can now be used with CSS variables and OKLCH colors. rgba function is still available as an alias for alpha function.

enhanceGetInputProps

@mantine/form now supports enhanceGetInputProps. enhanceGetInputProps is a function that can be used to add additional props to the object returned by form.getInputProps. You can define it in useForm hook options. Its argument is an object with the following properties:

  • inputProps – object returned by form.getInputProps by default
  • field – field path, first argument of form.getInputProps, for example name, user.email, users.0.name
  • options – second argument of form.getInputProps, for example { type: 'checkbox' }, can be used to pass additional options to enhanceGetInputProps function
  • form – form instance

Example of using enhanceGetInputProps to disable input based on field path:

import { NumberInput, TextInput } from '@mantine/core';
import { useForm } from '@mantine/form';

interface FormValues {
  name: string;
  age: number | string;
}

function Demo() {
  const form = useForm<FormValues>({
    mode: 'uncontrolled',
    initialValues: { name: '', age: '' },
    enhanceGetInputProps: (payload) => ({
      disabled: payload.field === 'name',
    }),
  });

  return (
    <>
      <TextInput
        {...form.getInputProps('name')}
        key={form.key('name')}
        label="Name"
        placeholder="Name"
      />
      <NumberInput
        {...form.getInputProps('age')}
        key={form.key('age')}
        label="Age"
        placeholder="Age"
        mt="md"
      />
    </>
  );
}

Example of using enhanceGetInputProps to add additional props to the input based on option passed to form.getInputProps:

Your personal information is stored securely. (Just kidding!)

import { NumberInput, TextInput } from '@mantine/core';
import { useForm } from '@mantine/form';

interface FormValues {
  name: string;
  age: number | string;
}

function Demo() {
  const form = useForm<FormValues>({
    mode: 'uncontrolled',
    initialValues: { name: '', age: '' },
    enhanceGetInputProps: (payload) => {
      if (payload.options.fieldType === 'name') {
        return {
          label: 'Your name',
          placeholder: 'Your name',
          withAsterisk: true,
          description: 'Your personal information is stored securely. (Just kidding!)',
        };
      }

      return {};
    },
  });

  return (
    <>
      <TextInput {...form.getInputProps('name', { fieldType: 'name' })} key={form.key('name')} />
      <NumberInput
        {...form.getInputProps('age')}
        key={form.key('age')}
        label="Age"
        placeholder="Age"
        mt="md"
      />
    </>
  );
}

form.initialize

@mantine/form now supports form.initialize handler.

When called form.initialize handler sets initialValues and values to the same value and marks form as initialized. It can be used only once, next form.initialize calls are ignored.

form.initialize is useful when you want to sync form values with backend API response:

import { Button, NumberInput, TextInput } from '@mantine/core';
import { isInRange, isNotEmpty, useForm } from '@mantine/form';

interface FormValues {
  name: string;
  age: number | string;
}

function apiRequest(): Promise<FormValues> {
  return new Promise((resolve) => {
    setTimeout(() => {
      resolve({ name: 'John Doe', age: 25 });
    }, 1000);
  });
}

function Demo() {
  const form = useForm<FormValues>({
    mode: 'uncontrolled',
    initialValues: { name: '', age: 0 },
    validate: {
      name: isNotEmpty('Name is required'),
      age: isInRange({ min: 18 }, 'You must be at least 18 to register'),
    },
  });

  return (
    <>
      <TextInput
        {...form.getInputProps('name')}
        key={form.key('name')}
        label="Name"
        placeholder="Name"
      />
      <NumberInput
        {...form.getInputProps('age')}
        key={form.key('age')}
        label="Age"
        placeholder="Age"
        mt="md"
      />
      <Button onClick={() => apiRequest().then((values) => form.initialize(values))} mt="md">
        Initialize form
      </Button>
    </>
  );
}

Example with TanStack Query (react-query):

import { useEffect } from 'react';
import { useQuery } from '@tanstack/react-query';
import { useForm } from '@mantine/form';

function Demo() {
  const query = useQuery({
    queryKey: ['current-user'],
    queryFn: () => fetch('/api/users/me').then((res) => res.json()),
  });

  const form = useForm({
    initialValues: {
      name: '',
      email: '',
    },
  });

  useEffect(() => {
    if (query.data) {
      // Even if query.data changes, form will be initialized only once
      form.initialize(query.data);
    }
  }, [query.data]);
}

Note that form.initialize will erase all values that were set before it was called. It is usually a good idea to set readOnly or disabled on all form fields before form.initialize is called to prevent data loss. You can implement this with enhanceGetInputProps:

import { NumberInput, TextInput, Button } from '@mantine/core';
import { useForm } from '@mantine/form';

interface FormValues {
  name: string;
  age: number | string;
}

function Demo() {
  const form = useForm<FormValues>({
    mode: 'uncontrolled',
    initialValues: { name: '', age: '' },
    enhanceGetInputProps: (payload) => {
      if (!payload.form.initialized) {
        return { disabled: true };
      }

      return {};
    },
  });

  return (
    <>
      <TextInput
        {...form.getInputProps('name')}
        key={form.key('name')}
        label="Your name"
        placeholder="Your name"
      />
      <NumberInput
        {...form.getInputProps('age')}
        key={form.key('age')}
        label="Age"
        placeholder="Age"
        mt="md"
      />
      <Button onClick={() => form.initialize({ name: 'John', age: 20 })} mt="md">
        Initialize form
      </Button>
    </>
  );
}

valibot form resolver

@mantine/form now supports validbot schema resolver:

yarn add valibot mantine-form-valibot-resolver

Basic fields validation:

import { valibotResolver } from 'mantine-form-valibot-resolver';
import {
  email,
  minLength,
  minValue,
  number,
  object,
  string,
} from 'valibot';
import { useForm } from '@mantine/form';

const schema = object({
  name: string([minLength(2, 'Name should have at least 2 letters')]),
  email: string([email('Invalid email')]),
  age: number([
    minValue(18, 'You must be at least 18 to create an account'),
  ]),
});

const form = useForm({
  initialValues: {
    name: '',
    email: '',
    age: 16,
  },
  validate: valibotResolver(schema),
});

form.validate();
form.errors;
// -> {
//  name: 'Name should have at least 2 letters',
//  email: 'Invalid email',
//  age: 'You must be at least 18 to create an account'
// }

Nested fields validation

import { valibotResolver } from 'mantine-form-valibot-resolver';
import { minLength, object, string } from 'valibot';
import { useForm } from '@mantine/form';

const nestedSchema = object({
  nested: object({
    field: string([
      minLength(2, 'Field should have at least 2 letters'),
    ]),
  }),
});

const form = useForm({
  initialValues: {
    nested: {
      field: '',
    },
  },
  validate: valibotResolver(nestedSchema),
});

form.validate();
form.errors;
// -> {
//  'nested.field': 'Field should have at least 2 letters',
// }

List fields validation:

import { valibotResolver } from 'mantine-form-valibot-resolver';
import { array, minLength, object, string } from 'valibot';
import { useForm } from '@mantine/form';

const listSchema = object({
  list: array(
    object({
      name: string([
        minLength(2, 'Name should have at least 2 letters'),
      ]),
    })
  ),
});

const form = useForm({
  initialValues: {
    list: [{ name: '' }],
  },
  validate: valibotResolver(listSchema),
});

form.validate();
form.errors;
// -> {
//  'list.0.name': 'Name should have at least 2 letters',
// }

ScrollArea scrollbars prop

ScrollArea now supports scrollbars prop, which allows controlling directions at which scrollbars should be rendered. Supported values are x, y and xy. If scrollbars="y" is set, only the vertical scrollbar will be rendered, and it will not be possible to scroll horizontally:

Charizard (Pokémon)

Charizard description from Bulbapedia

Charizard is a draconic, bipedal Pokémon. It is primarily orange with a cream underside from the chest to the tip of its tail. It has a long neck, small blue eyes, slightly raised nostrils, and two horn-like structures protruding from the back of its rectangular head. There are two fangs visible in the upper jaw when its mouth is closed. Two large wings with blue-green undersides sprout from its back, and a horn-like appendage juts out from the top of the third joint of each wing. A single wing-finger is visible through the center of each wing membrane. Charizard's arms are short and skinny compared to its robust belly, and each limb has three white claws. It has stocky legs with cream-colored soles on each of its plantigrade feet. The tip of its long, tapering tail burns with a sizable flame.

As Mega Charizard X, its body and legs are more physically fit, though its arms remain thin. Its skin turns black with a sky-blue underside and soles. Two spikes with blue tips curve upward from the front and back of each shoulder, while the tips of its horns sharpen, turn blue, and curve slightly upward. Its brow and claws are larger, and its eyes are now red. It has two small, fin-like spikes under each horn and two more down its lower neck. The finger disappears from the wing membrane, and the lower edges are divided into large, rounded points. The third joint of each wing-arm is adorned with a claw-like spike. Mega Charizard X breathes blue flames out the sides of its mouth, and the flame on its tail now burns blue. It is said that its new power turns it black and creates more intense flames.

import { ScrollArea, Box } from '@mantine/core';

function Demo() {
  return (
    <ScrollArea w={300} h={200} scrollbars="y">
      <Box w={600}>
        {/* ... content */}
      </Box>
    </ScrollArea>
  );
}

Title lineClamp prop

Title component now supports lineClamp prop, which allows truncating text after a specified number of lines:

Lorem ipsum dolor sit amet consectetur adipisicing elit. Iure doloremque quas dolorum. Quo amet earum alias consequuntur quam accusamus a quae beatae, odio, quod provident consectetur non repudiandae enim adipisci?

Line clamp
import { Title, Box } from '@mantine/core';

function Demo() {
  return (
    <Box maw={400}>
      <Title order={2} lineClamp={2}>
        Lorem ipsum dolor sit amet consectetur adipisicing elit. Iure doloremque quas dolorum. Quo
        amet earum alias consequuntur quam accusamus a quae beatae, odio, quod provident consectetur
        non repudiandae enim adipisci?
      </Title>
    </Box>
  )
}

Help center

Help center is a new website with guides, tutorials and frequently asked questions. Currently, it has 14 questions, more FAQs will be added in the next releases.

Documentation updates

  • form.getInputProps guide now has a separate page. It describes form.getInputProps, enhanceGetInputProps and how to integrate form.getInputProps with custom inputs.
  • assignRef function documentation has been added.
  • clampUseMovePosition function documentation has been added.
  • Additional documentation about hook arguments and types has been added to use-hotkeys.
  • UseListStateHandlers type documentation has been added.
  • Functions reference page has been added. Currently, it contains all functions that are exported from @mantine/hooks package. It is planned to document functions from other packages in next releases.
  • Examples on how to change the close icon have been added to Drawer and Modal components.
  • variantColorsResolver demos have been added to ActionIcon, ThemeIcon and Badge components.

Other changes

  • RichTextEditor no longer depends on @tabler/icons package. It is no longer required to install @tabler/icons package to use RichTextEditor component. Icons used in the editor are now a part of the @mantine/tiptap package. This change improves bundling performance in several cases (mostly when using RichTextEditor in Next.js apps).
  • Badge component now supports circle prop which makes the badge round.
  • You can now reference theme values in ff style prop with mono, text and heading values: <Box ff="mono" />.
  • RichTextEditor now has RichTextEditor.Undo and RichTextEditor.Redo controls.
  • A new luminance color function was added. It returns color luminance as a number between 0 and 1.
  • All components now support new flex style prop which allows setting flex CSS property on the root element.
  • Collapse markup was reduced to single element, it can now be used in contexts that were previously not supported, for example, table rows.
  • stepHoldDelay and stepHoldInterval props have been added to NumberInput.
  • mantine-form-zod-resolver now supports errorPriority configuration which allows controlling the order of errors specified in the schema. This feature requires updating mantine-form-zod-resolver to version 1.1.0 or higher.
  • CloseButton now supports icon prop, which allows overriding default icon. It is useful when it is not possible to replace CloseButton, for example, in Drawer component.
  • Select component now calls onChange with an additional argument – option object. It contains label, value and optional disabled properties.
  • It is now possible to define CSS variables in styles prop of all components.
  • New use-in-viewport hook
  • All Vite templates have been updated to Vite 5.0 and Vitest 1.0
