Alpha version

This is the first alpha version of Mantine 9. You are welcome to review changes and provide feedback.

Support Mantine development

You can now sponsor Mantine development with OpenCollective.
All funds are used to improve Mantine and create new features and components.

Migration guide

This changelog covers breaking changes and new features in Mantine 9.0.
To migrate your application to Mantine 9.0, follow 8.x → 9.x migration guide.

Peer dependencies requirements updates

Starting from Mantine 9.0, the following dependencies are required:

• React 19+ for all @mantine/* packages
• Tiptap 3+ for @mantine/tiptap (migration guide)
• Recharts 3+ for @mantine/charts (no migration required)

Namespace types exports

All Mantine components and hooks now provide namespace exports for related types.
For example, use-disclosure hook types can now be accessed like this:

import { useDisclosure } from '@mantine/hooks';

const options: useDisclosure.Options = {
  onOpen: () => console.log('open'),
  onClose: () => console.log('close'),
};

function Demo() {
  const [opened, handlers] = useDisclosure(options);
}

Example of using namespace types with Button props type:

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

const buttonProps: Button.Props = {
    variant: 'filled',
    size: 'md',
    disabled: false,
  };

function Demo() {
  return <Button {...buttonProps}>Click me</Button>;
}

New @mantine/schedule package

New @mantine/schedule package provides a complete set of
calendar scheduling components for React applications. It includes multiple view levels,
drag-and-drop event management, and extensive customization options.

Components included:

• Schedule – unified container component that combines all views with built-in navigation and view switching
• DayView – single day view with configurable time slots, all-day event section, current time indicator, and business hours highlighting
• WeekView – weekly calendar grid with time slots, week numbers, weekend day toggling, and multi-day event spanning
• MonthView – monthly calendar grid with event overflow handling, outside days display, and week numbers
• YearView – 12-month year overview organized by quarters with day-level event indicators
• MobileMonthView – mobile-optimized month view with event details panel for the selected day

Key features:

• Drag and drop – drag events to reschedule them across time slots and days. Supports conditional dragging with canDragEvent callback, and drag-to-select time ranges with withDragSlotSelect
• Multiple interaction modes – default mode enables all interactions (click, drag, navigation), static mode renders a read-only calendar
• Responsive layout – layout="responsive" automatically switches to YearView and MobileMonthView on smaller screens
• Custom event rendering – use renderEventBody or renderEvent to fully customize how events are displayed in all views
• Time configuration – configurable start/end times, time slot intervals, time label formats, and business hours highlighting
• Internationalization – full label customization through the labels prop, locale-aware date formatting via dayjs
• Click handlers – onTimeSlotClick, onAllDaySlotClick, onDayClick, and onEventClick for building interactive scheduling interfaces
• Styles API – full support for classNames, styles, and unstyled props, along with CSS variables for theming

To get started, follow the getting started guide.

Collapse horizontal orientation

Collapse component now supports horizontal orientation:

import { Button, Collapse, Stack, Typography } from '@mantine/core';
import { useDisclosure } from '@mantine/hooks';

function Demo() {
  const [expanded, handlers] = useDisclosure(false);

  return (
    <Stack h={240} align="flex-start">
      <Button onClick={handlers.toggle} w="fit-content">
        {expanded ? 'Collapse' : 'Expand'}
      </Button>

      <Collapse expanded={expanded} orientation="horizontal">
        <Typography bg="var(--mantine-color-blue-light)" p="xs" bdrs="md" w={200}>
          Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt
          ut labore et dolore magna aliqua.
        </Typography>
      </Collapse>
    </Stack>
  );
}

use-collapse and use-horizontal-collapse hooks

New use-collapse hook is the hook version of Collapse component.
It allows animation of height from 0 to auto and vice versa.

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

function Demo() {
  const [expanded, handlers] = useDisclosure(false);
  const getCollapseProps = useCollapse({ expanded });

  return (
    <>
      <Button onClick={handlers.toggle} mb="md">
        {expanded ? 'Collapse' : 'Expand'}
      </Button>

      <div {...getCollapseProps()}>
        <Typography bg="var(--mantine-color-blue-light)" p="xs" bdrs="md">
          Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt
          ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation
          ullamco laboris nisi ut aliquip ex ea commodo consequat.
        </Typography>
      </div>
    </>
  );
}

use-horizontal-collapse works the same way as use-collapse but animates width instead of height:

import { Button, Stack, Typography } from '@mantine/core';
import { useDisclosure, useHorizontalCollapse } from '@mantine/hooks';

function Demo() {
  const [expanded, handlers] = useDisclosure(false);
  const { getCollapseProps } = useHorizontalCollapse({ expanded });

  return (
    <Stack h={240}>
      <Button onClick={handlers.toggle} w="fit-content">
        {expanded ? 'Collapse' : 'Expand'}
      </Button>

      <div {...getCollapseProps()}>
        <Typography bg="var(--mantine-color-blue-light)" p="xs" bdrs="md" w={200}>
          Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt
          ut labore et dolore magna aliqua.
        </Typography>
      </div>
    </Stack>
  );
}

use-floating-window hook

New use-floating-window hook allows creating floating draggable
elements:

import { Button, CloseButton, Group, Paper, Portal, Text } from '@mantine/core';
import { useDisclosure, useFloatingWindow } from '@mantine/hooks';

function Demo() {
  const [visible, handlers] = useDisclosure();
  const floatingWindow = useFloatingWindow({
    constrainToViewport: true,
    constrainOffset: 20,
    excludeDragHandleSelector: 'button',
    initialPosition: { top: 300, left: 20 },
  });

  return (
    <>
      <Button onClick={handlers.toggle} variant="default">
        {visible ? 'Hide' : 'Show'} floating window
      </Button>

      {visible && (
        <Portal>
          <Paper
            w={280}
            p="md"
            withBorder
            radius="md"
            pos="fixed"
            style={{ cursor: 'move', transition: 'box-shadow 70ms ease', zIndex: 400 }}
            shadow={floatingWindow.isDragging ? 'md' : undefined}
            ref={floatingWindow.ref}
          >
            <Group justify="space-between" mb="md">
              <Text>Usage demo</Text>
              <CloseButton onClick={handlers.close} />
            </Group>
            <Text fz="sm">This is a floating window. You can drag it around.</Text>
          </Paper>
        </Portal>
      )}
    </>
  );
}

FloatingWindow component

FloatingWindow provides component API for use-floating-window hook:

import { Button, CloseButton, FloatingWindow, Group, Text } from '@mantine/core';
import { useDisclosure } from '@mantine/hooks';

function Demo() {
  const [visible, handlers] = useDisclosure();

  return (
    <>
      <Button onClick={handlers.toggle} variant="default">
        {visible ? 'Hide' : 'Show'} floating window
      </Button>

      {visible && (
        <FloatingWindow
          w={280}
          p="md"
          withBorder
          radius="md"
          excludeDragHandleSelector="button"
          initialPosition={{ top: 300, left: 20 }}
          style={{ cursor: 'move' }}
        >
          <Group justify="space-between" mb="md">
            <Text>Usage demo</Text>
            <CloseButton onClick={handlers.close} />
          </Group>
          <Text fz="sm">This is a floating window. You can drag it around.</Text>
        </FloatingWindow>
      )}
    </>
  );
}

OverflowList component

New OverflowList component displays list of items and collapses the overflowing items into a single element:

// OverflowListDemo.tsx
import { Badge, OverflowList } from '@mantine/core';
import { data } from './data';

function Demo() {
  return (
    <div style={{ resize: 'horizontal', overflow: 'auto', maxWidth: '100%' }}>
      <OverflowList
        data={data}
        gap={4}
        renderOverflow={(items) => <Badge>+{items.length} more</Badge>}
        renderItem={(item, index) => <Badge key={index}>{item}</Badge>}
      />
    </div>
  );
}

// data.ts
export const data = [
  'Apple',
  'Banana',
  'Cherry',
  'Date',
  'Elderberry',
  'Fig',
  'Grape',
  'Honeydew',
  'Indian Fig',
  'Jackfruit',
  'Kiwi',
  'Lemon',
  'Mango',
  'Nectarine',
  'Orange',
  'Papaya',
];

Card horizontal orientation

Card component now supports horizontal orientation:

import { Box, Card, Group, RingProgress, Text } from '@mantine/core';

const completed = 1887;
const total = 2334;
const stats = [
  { value: 447, label: 'Remaining' },
  { value: 76, label: 'In progress' },
];

function Demo() {
  const items = stats.map((stat) => (
    <div key={stat.label}>
      <Text>{stat.value}</Text>
      <Text size="xs" c="dimmed">
        {stat.label}
      </Text>
    </div>
  ));

  return (
    <Card padding="sm" radius="md" withBorder orientation="horizontal">
      <Card.Section inheritPadding px="xs" withBorder>
        <RingProgress
          roundCaps
          thickness={6}
          size={150}
          sections={[{ value: (completed / total) * 100, color: 'blue' }]}
          label={
            <div>
              <Text ta="center" fz="lg">
                {((completed / total) * 100).toFixed(0)}%
              </Text>
              <Text ta="center" fz="xs" c="dimmed">
                Completed
              </Text>
            </div>
          }
        />
      </Card.Section>

      <Card.Section inheritPadding px="md">
        <Text fz="xl">Project tasks</Text>
        <Box mt="xs">
          <Text>1887</Text>
          <Text fz="xs" c="dimmed">
            Completed
          </Text>
        </Box>

        <Group mt="sm">{items}</Group>
      </Card.Section>
    </Card>
  );
}

Checkbox.Group and Switch.Group maxSelectedValues

Checkbox.Group and Switch.Group now support maxSelectedValues prop to limit the number of selected values.
When the limit is reached, the remaining controls are disabled and cannot be selected.

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

function Demo() {
  return (
    <Checkbox.Group defaultValue={['react']} maxSelectedValues={2}>
      <Group>
        <Checkbox value="react" label="React" />
        <Checkbox value="svelte" label="Svelte" />
        <Checkbox value="ng" label="Angular" />
        <Checkbox value="vue" label="Vue" />
      </Group>
    </Checkbox.Group>
  );
}

Inputs loading state

All Mantine input components based on Input component now support loading prop.

Set loading prop to display a loading indicator. By default, the loader is displayed on the right side of the input.
You can change the position with the loadingPosition prop to 'left' or 'right'. This is useful for async operations like API calls, searches, or validations:

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

function Demo() {
  return <TextInput placeholder="Your email" loading />;
}

renderPill in MultiSelect and TagsInput

MultiSelect and TagsInput components now support renderPill prop to customize pill rendering:

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

const users = [
  { value: 'Emily Johnson', label: 'Emily Johnson', image: 'https://raw.githubusercontent.com/mantinedev/mantine/master/.demo/avatars/avatar-7.png' },
  { value: 'Ava Rodriguez', label: 'Ava Rodriguez', image: 'https://raw.githubusercontent.com/mantinedev/mantine/master/.demo/avatars/avatar-8.png' },
  { value: 'Olivia Chen', label: 'Olivia Chen', image: 'https://raw.githubusercontent.com/mantinedev/mantine/master/.demo/avatars/avatar-4.png' },
  { value: 'Ethan Barnes', label: 'Ethan Barnes', image: 'https://raw.githubusercontent.com/mantinedev/mantine/master/.demo/avatars/avatar-1.png' },
  { value: 'Mason Taylor', label: 'Mason Taylor', image: 'https://raw.githubusercontent.com/mantinedev/mantine/master/.demo/avatars/avatar-2.png' },
];

function Demo() {
  return (
    <MultiSelect
      data={users}
      label="Candidates"
      placeholder="Select candidates"
      defaultValue={['Emily Johnson', 'Ava Rodriguez']}
      renderPill={({ option, onRemove }) => {
        const user = users.find((u) => u.value === option?.value);
        return (
          <Pill withRemoveButton onRemove={onRemove}>
            <div style={{ display: 'flex', alignItems: 'center', gap: 8 }}>
              <Avatar src={user?.image} size={16} />
              {option?.label}
            </div>
          </Pill>
        );
      }}
    />
  );
}

Clear section mode

All clearable input components now support clearSectionMode prop that determines how the clear button and rightSection are rendered:

• 'both' (default) – render both the clear button and rightSection
• 'rightSection' – render only the user-supplied rightSection, ignore clear button
• 'clear' – render only the clear button, ignore rightSection

This prop is supported by Select, Autocomplete,
MultiSelect, TagsInput, FileInput,
DateInput, DatePickerInput,
MonthPickerInput, YearPickerInput,
TimePicker, and DateTimePicker.

import { IconChevronDown } from '@tabler/icons-react';
import { Stack } from '@mantine/core';
import { DatePickerInput } from '@mantine/dates';

function Demo() {
  return (
    <Stack>
      <DatePickerInput
        label="clearSectionMode='both' (default)"
        placeholder="Pick date"
        defaultValue={new Date()}
        clearable
        rightSection={<IconChevronDown size={16} />}
        clearSectionMode="both"
      />

      <DatePickerInput
        label="clearSectionMode='rightSection'"
        placeholder="Pick date"
        defaultValue={new Date()}
        clearable
        rightSection={<IconChevronDown size={16} />}
        clearSectionMode="rightSection"
      />

      <DatePickerInput
        label="clearSectionMode='clear'"
        placeholder="Pick date"
        defaultValue={new Date()}
        clearable
        rightSection={<IconChevronDown size={16} />}
        clearSectionMode="clear"
      />
    </Stack>
  );
}

Marquee component

New Marquee component creates continuous scrolling animation for content:

import { Marquee } from '@mantine/core';
import { MantineLogo } from '@mantinex/mantine-logo';

function Demo() {
  return (
    <Marquee gap="lg">
      <MantineLogo width={80} type="full" color="blue" />
      <MantineLogo width={80} type="full" color="cyan" />
      <MantineLogo width={80} type="full" color="teal" />
      <MantineLogo width={80} type="full" color="green" />
      <MantineLogo width={80} type="full" color="lime" />
      <MantineLogo width={80} type="full" color="yellow" />
      <MantineLogo width={80} type="full" color="orange" />
      <MantineLogo width={80} type="full" color="red" />
    </Marquee>
  );
}

Scroller component

New Scroller component displays horizontally scrollable content with navigation controls.
It supports native scrolling via trackpad, shift + mouse wheel, touch gestures, and mouse drag:

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

function Demo() {
  return (
    <Scroller>
      <Group gap="xs" wrap="nowrap">
        {Array.from({ length: 20 }).map((_, index) => (
          <Badge key={index} variant="light" size="lg">
            Badge {index + 1}
          </Badge>
        ))}
      </Group>
    </Scroller>
  );
}

use-scroller hook

New use-scroller hook provides logic for creating custom scrollable containers with navigation controls:

import { Box, Button, Group } from '@mantine/core';
import { useScroller } from '@mantine/hooks';

function Demo() {
  const scroller = useScroller();

  return (
    <Box>
      <Group mb="md">
        <Button
          onClick={scroller.scrollStart}
          disabled={!scroller.canScrollStart}
          variant="default"
          size="xs"
        >
          ← Scroll left
        </Button>
        <Button
          onClick={scroller.scrollEnd}
          disabled={!scroller.canScrollEnd}
          variant="default"
          size="xs"
        >
          Scroll right →
        </Button>
      </Group>

      <div
        ref={scroller.ref}
        {...scroller.dragHandlers}
        style={{
          overflow: 'auto',
          cursor: scroller.isDragging ? 'grabbing' : 'grab',
        }}
      >
        <Group wrap="nowrap" gap="md">
          {Array.from({ length: 20 }).map((_, index) => (
            <Box
              key={index}
              style={{
                minWidth: 100,
                height: 80,
                backgroundColor: 'var(--mantine-color-blue-filled)',
                borderRadius: 'var(--mantine-radius-md)',
                display: 'flex',
                alignItems: 'center',
                justifyContent: 'center',
                color: 'white',
                fontWeight: 500,
              }}
            >
              {index + 1}
            </Box>
          ))}
        </Group>
      </div>
    </Box>
  );
}

use-form TransformedValues type argument

use-form now supports passing second type argument TransformedValues to define the type of
transformed values returned by form.getTransformedValues and form.onSubmit:

import { useForm } from '@mantine/form';

interface FormValues {
  name: string;
  locationId: string;
}

interface TransformedValues {
  name: string;
  locationId: number;
}

function Demo() {
  const form = useForm<FormValues, TransformedValues>({
    mode: 'uncontrolled',
    initialValues: {
      name: '',
      locationId: '2',
    },

    transformValues: (values) => ({
      ...values,
      locationId: Number(values.locationId),
    }),
  });
}

use-form async validation

use-form validation rules can now be async – return a Promise that resolves to an
error message or null. When any rule is async, form.validate(), form.validateField() and
form.isValid() all return promises. The form.validating property is true while any async
validation is in progress, and form.isValidating(path) checks individual fields.

Each rule receives an AbortSignal as the fourth argument. The signal is aborted when a newer
validation supersedes the current one, which you can use to cancel in-flight HTTP requests.

import { Button, Group, Loader, TextInput } from '@mantine/core';
import { isEmail, useForm } from '@mantine/form';

// Simulates an async API call to check if the username is available
function checkUsernameAvailability(username: string, signal?: AbortSignal): Promise<string | null> {
  return new Promise((resolve, reject) => {
    const timer = setTimeout(() => {
      const taken = ['admin', 'user', 'test', 'mantine'];
      resolve(taken.includes(username.toLowerCase()) ? 'Username is already taken' : null);
    }, 800);

    signal?.addEventListener('abort', () => {
      clearTimeout(timer);
      reject(new DOMException('Aborted', 'AbortError'));
    });
  });
}

function Demo() {
  const form = useForm({
    mode: 'uncontrolled',
    initialValues: { username: '', email: '' },
    validate: {
      username: async (value, _values, _path, signal) => {
        if (value.trim().length < 3) {
          return 'Username must be at least 3 characters';
        }
        return checkUsernameAvailability(value, signal);
      },
      email: isEmail('Invalid email'),
    },
  });

  return (
    <form onSubmit={form.onSubmit((values) => console.log(values))}>
      <TextInput
        withAsterisk
        label="Username"
        placeholder="Pick a username"
        key={form.key('username')}
        disabled={form.submitting}
        rightSection={form.validating ? <Loader size={16} /> : null}
        {...form.getInputProps('username')}
      />

      <TextInput
        withAsterisk
        mt="md"
        label="Email"
        placeholder="your@email.com"
        key={form.key('email')}
        disabled={form.submitting}
        {...form.getInputProps('email')}
      />

      <Group justify="flex-end" mt="md">
        <Button type="submit" loading={form.submitting}>
          Submit
        </Button>
      </Group>
    </form>
  );
}

When using async validation with validateInputOnChange, set validateDebounce to avoid
firing an API call on every keystroke:

import { Button, Group, Loader, TextInput } from '@mantine/core';
import { useForm, isEmail } from '@mantine/form';

// Simulates an async API call to check if the username is available
function checkUsernameAvailability(username: string, signal?: AbortSignal): Promise<string | null> {
  return new Promise((resolve, reject) => {
    const timer = setTimeout(() => {
      const taken = ['admin', 'user', 'test', 'mantine'];
      resolve(taken.includes(username.toLowerCase()) ? 'Username is already taken' : null);
    }, 800);

    signal?.addEventListener('abort', () => {
      clearTimeout(timer);
      reject(new DOMException('Aborted', 'AbortError'));
    });
  });
}

function Demo() {
  const form = useForm({
    mode: 'uncontrolled',
    initialValues: { username: '', email: '' },

    // Debounce async validation by 500ms – prevents firing
    // an API call on every keystroke
    validateDebounce: 500,
    validateInputOnChange: ['username'],

    validate: {
      username: async (value, _values, _path, signal) => {
        if (value.trim().length < 3) {
          return 'Username must be at least 3 characters';
        }
        return checkUsernameAvailability(value, signal);
      },
      email: isEmail('Invalid email'),
    },
  });

  return (
    <form onSubmit={form.onSubmit((values) => console.log(values))}>
      <TextInput
        withAsterisk
        label="Username"
        description="Try: admin, user, test, mantine"
        placeholder="Pick a username"
        key={form.key('username')}
        disabled={form.submitting}
        rightSection={form.isValidating('username') ? <Loader size={16} /> : null}
        {...form.getInputProps('username')}
      />

      <TextInput
        withAsterisk
        mt="md"
        label="Email"
        placeholder="your@email.com"
        key={form.key('email')}
        disabled={form.submitting}
        {...form.getInputProps('email')}
      />

      <Group justify="flex-end" mt="md">
        <Button type="submit" loading={form.submitting}>
          Submit
        </Button>
      </Group>
    </form>
  );
}

Generic components

SegmentedControl, Select, MultiSelect,
Chip.Group, Switch.Group, Checkbox.Group and Radio.Group
now support generic value type. You can pass primitive values (numbers, strings, boolean, null)
as the type argument. The generic type is used for value, defaultValue, onChange and other props.

For example, generic type can now be used with SegmentedControl
to specify string union:

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

function Demo() {
  return (
    <SegmentedControl<'orange' | 'grape' | 'apple'>
      data={[
        { value: 'orange', label: 'Orange' },
        { value: 'grape', label: 'Grape' },
        { value: 'apple', label: 'Apple' },
      ]}
    />
  );
}

Combobox virtualization (alpha)

Combobox component now supports virtualization.
Virtualization support is currently in alpha stage and the API may change in future releases. You
are welcome to try it out and provide feedback.

Example of implementation with useVirtualizedCombobox and react-virtuoso:

import { useRef, useState } from 'react';
import { ListRange, Virtuoso } from 'react-virtuoso';
import { Combobox, Input, InputBase, ScrollArea, useVirtualizedCombobox } from '@mantine/core';

const largeData = Array(10000)
  .fill(0)
  .map((_, index) => ({
    value: `value-${index}`,
    label: `Label ${index}`,
    id: `item-${index}`,
    disabled: false,
  }));

function Demo() {
  const [opened, setOpened] = useState(false);
  const [selectedOptionIndex, setSelectedOptionIndex] = useState(0);
  const [activeOptionIndex, setActiveOptionIndex] = useState(-1);
  const [value, setValue] = useState('');
  const virtuoso = useRef<any>(null);
  const viewportRef = useRef<HTMLDivElement>(null);
  const visibleRangeRef = useRef<ListRange>({
    startIndex: 0,
    endIndex: 0,
  });

  const scrollOptionIntoView = (index: number) => {
    setTimeout(() => {
      const isVisible =
        index >= visibleRangeRef.current.startIndex && index <= visibleRangeRef.current.endIndex;
      if (index !== -1 && !isVisible) {
        virtuoso.current.scrollToIndex({ index, align: 'end' });
      }
    }, 4);
  };

  const combobox = useVirtualizedCombobox({
    opened,
    onOpenedChange: setOpened,
    onDropdownOpen: () => {
      if (activeOptionIndex !== -1) {
        combobox.selectActiveOption();
        scrollOptionIntoView(activeOptionIndex);
      }
    },
    isOptionDisabled: (index) => largeData[index].disabled,
    totalOptionsCount: largeData.length,
    getOptionId: (index) => largeData[index].id,
    selectedOptionIndex,
    activeOptionIndex,
    setSelectedOptionIndex: (index) => {
      setSelectedOptionIndex(index);
      scrollOptionIntoView(index);
    },
    onSelectedOptionSubmit: onOptionSubmit,
  });

  function onOptionSubmit(index: number) {
    const option = largeData[index];
    setValue(option.value);
    setActiveOptionIndex(index);
    combobox.closeDropdown();
    combobox.resetSelectedOption();
  }

  return (
    <Combobox
      store={combobox}
      resetSelectionOnOptionHover={false}
      keepMounted
      onOptionSubmit={(option) => {
        setValue(option);
        combobox.openDropdown();
      }}
    >
      <Combobox.Target>
        <InputBase component="button" onClick={() => combobox.toggleDropdown()} pointer>
          {value || <Input.Placeholder>Pick a value</Input.Placeholder>}
        </InputBase>
      </Combobox.Target>
      <Combobox.Dropdown>
        <Combobox.Options>
          <ScrollArea.Autosize
            mah={220}
            type="scroll"
            scrollbarSize={4}
            viewportRef={viewportRef}
            onMouseDown={(event) => event.preventDefault()}
          >
            <Virtuoso
              data={largeData}
              ref={virtuoso}
              style={{ height: 420 }}
              customScrollParent={viewportRef.current!}
              rangeChanged={(range) => {
                visibleRangeRef.current = range;
              }}
              itemContent={(index, item) => (
                <Combobox.Option
                  value={item.value}
                  key={item.value}
                  selected={index === selectedOptionIndex}
                  onClick={() => onOptionSubmit(index)}
                >
                  {item.label}
                </Combobox.Option>
              )}
            />
          </ScrollArea.Autosize>
        </Combobox.Options>
      </Combobox.Dropdown>
    </Combobox>
  );
}

Highlight per-term colors

Highlight component now supports custom colors for individual highlight terms.
You can provide an array of objects with text and color properties to assign different colors
to different highlighted terms:

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

function Demo() {
  return (
    <Highlight
      highlight={[
        { text: 'error', color: 'red' },
        { text: 'warning', color: 'yellow' },
        { text: 'success', color: 'green' },
      ]}
    >
      Error: Invalid input. Warning: Check this field. Success: All tests passed.
    </Highlight>
  );
}

Highlight whole-word matching

Highlight component now supports wholeWord prop to match only complete words.
When enabled, 'the' will not match 'there' or 'theme':

import { Highlight, Stack, Text } from '@mantine/core';

function Demo() {
  return (
    <Stack gap="md">
      <div>
        <Text size="sm" fw={500} mb={5}>
          With whole word matching (wholeWord={'{'}true{'}'})
        </Text>
        <Highlight highlight="the" wholeWord>
          The theme is there
        </Highlight>
      </div>

      <div>
        <Text size="sm" fw={500} mb={5}>
          Without whole word matching (default)
        </Text>
        <Highlight highlight="the">The theme is there</Highlight>
      </div>
    </Stack>
  );
}

Pagination and use-pagination startValue

Pagination component and use-pagination hook now support startValue prop
to define the starting page number. For example, with startValue={5} and total={15},
the pagination range will be from 5 to 15:

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

function Demo() {
  return (
    <>
      <Text mb="xs">Pages 5–15 (startValue=5, total=15)</Text>
      <Pagination total={15} startValue={5} defaultValue={5} />
    </>
  );
}

Grid improvements

Grid component no longer uses negative margins for spacing between columns.
Instead, it now uses native CSS gap property, which means you no longer need to use
overflow="hidden" to prevent content overflow caused by negative margins.

Slider vertical orientation

Slider and RangeSlider components now support vertical orientation:

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

const marks = [
  { value: 20, label: '20%' },
  { value: 50, label: '50%' },
  { value: 80, label: '80%' },
];

function Demo() {
  return (
    <div style={{ display: 'flex', gap: 40 }}>
      <Slider orientation="vertical" defaultValue={45} marks={marks} />
      <RangeSlider orientation="vertical" defaultValue={[25, 65]} marks={marks} />
    </div>
  );
}

SimpleGrid improvements

SimpleGrid component now supports minColWidth prop to use CSS Grid auto-fill/auto-fit
to automatically adjust the number of columns based on available space and minimum column width.
When minColWidth is set, the cols prop is ignored. Use autoFlow prop to switch between
auto-fill (default) and auto-fit behavior.

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

function Demo() {
  return (
    <SimpleGrid minColWidth="200px">
      <div>1</div>
      <div>2</div>
      <div>3</div>
      <div>4</div>
      <div>5</div>
    </SimpleGrid>
  );
}

SimpleGrid also now supports autoRows prop to control the size of
implicitly created grid rows:

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

function Demo() {
  return (
    <SimpleGrid cols={3} autoRows="minmax(100px, auto)">
      <div>1</div>
      <div>2</div>
      <div>3</div>
      <div>4</div>
      <div>5</div>
    </SimpleGrid>
  );
}

BarsList component

New BarsList component displays a list of horizontal bars with names and values.
It supports custom colors, auto contrast, value formatting, and custom bar rendering:

// Demo.tsx
import { BarsList } from '@mantine/charts';
import { data } from './data';

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

// data.ts
export const data = ${JSON.stringify(data, null, 2)};

[dmitri-gb]

@rtivital What do you think about making withAlignedLabels={true} the default in Select and MultiSelect components?

with-aligned-labels.mp4

[navid70]

can we have native support for Jalali and other calendars in v9?

[rtivital]

I do not plan to work on this because I do not use the Jalali calendar in my work.

[robin-dongbin]

Is there still no plan to add an official datatable component?

[rtivital]

In 9.0 no, I'm planning to work on it later in 9.x or 10.0 release
