use-scroll-spy hook

New use-scroll-spy hook tracks scroll position and returns index of the
element that is currently in the viewport. It is useful for creating
table of contents components (like in mantine.dev sidebar on the right side)
and similar features.

import { Text, UnstyledButton } from '@mantine/core';
import { useScrollSpy } from '@mantine/hooks';

function Demo() {
  const spy = useScrollSpy({
    selector: '#mdx :is(h1, h2, h3, h4, h5, h6)',
  });

  const headings = spy.data.map((heading, index) => (
    <li
      key={heading.id}
      style={{
        listStylePosition: 'inside',
        paddingInlineStart: heading.depth * 20,
        background: index === spy.active ? 'var(--mantine-color-blue-light)' : undefined,
      }}
    >
      <UnstyledButton onClick={() => heading.getNode().scrollIntoView()}>
        {heading.value}
      </UnstyledButton>
    </li>
  ));

  return (
    <div>
      <Text>Scroll to heading:</Text>
      <ul style={{ margin: 0, padding: 0 }}>{headings}</ul>
    </div>
  );
}

TableOfContents component

New TableOfContents component is built on top of use-scroll-spy hook
and can be used to create table of contents components like the one on the right side of mantine.dev
documentation sidebar:

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

function Demo() {
  return (
    <TableOfContents
      variant="filled"
      color="blue"
      size="sm"
      radius="sm"
      scrollSpyOptions={{
        selector: '#mdx :is(h1, h2, h3, h4, h5, h6)',
      }}
      getControlProps={({ data }) => ({
        onClick: () => data.getNode().scrollIntoView(),
        children: data.value,
      })}
    />
  );
}

Input.ClearButton component

New Input.ClearButton component can be used to add clear button to custom inputs
based on Input component. size of the clear button is automatically
inherited from the input:

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

function Demo() {
  const [value, setValue] = useState('clearable');

  return (
    <Input
      placeholder="Clearable input"
      value={value}
      onChange={(event) => setValue(event.currentTarget.value)}
      rightSection={value !== '' ? <Input.ClearButton onClick={() => setValue('')} /> : undefined}
      rightSectionPointerEvents="auto"
      size="sm"
    />
  );
}

Popover with overlay

Popover and other components based on it now support withOverlay prop:

import { Anchor, Avatar, Group, Popover, Stack, Text } from '@mantine/core';

function Demo() {
  return (
    <Popover
      width={320}
      shadow="md"
      withArrow
      withOverlay
      overlayProps={{ zIndex: 10000, blur: '8px' }}
      zIndex={10001}
    >
      <Popover.Target>
        <UnstyledButton style={{ zIndex: 10001, position: 'relative' }}>
          <Avatar src="https://avatars.githubusercontent.com/u/79146003?s=200&v=4" radius="xl" />
        </UnstyledButton>
      </Popover.Target>
      <Popover.Dropdown>
        <Group>
          <Avatar src="https://avatars.githubusercontent.com/u/79146003?s=200&v=4" radius="xl" />
          <Stack gap={5}>
            <Text size="sm" fw={700} style={{ lineHeight: 1 }}>
              Mantine
            </Text>
            <Anchor href="https://x.com/mantinedev" c="dimmed" size="xs" style={{ lineHeight: 1 }}>
              @mantinedev
            </Anchor>
          </Stack>
        </Group>

        <Text size="sm" mt="md">
          Customizable React components and hooks library with focus on usability, accessibility and
          developer experience
        </Text>

        <Group mt="md" gap="xl">
          <Text size="sm">
            <b>0</b> Following
          </Text>
          <Text size="sm">
            <b>1,174</b> Followers
          </Text>
        </Group>
      </Popover.Dropdown>
    </Popover>
  );
}

Container queries in Carousel

You can now use container queries
in Carousel 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 { Carousel } from '@mantine/carousel';

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%',
        minWidth: 250,
        padding: 10,
      }}
    >
      <Carousel
        withIndicators
        height={200}
        type="container"
        slideSize={{ base: '100%', '300px': '50%', '500px': '33.333333%' }}
        slideGap={{ base: 0, '300px': 'md', '500px': 'lg' }}
        loop
        align="start"
      >
        <Carousel.Slide>1</Carousel.Slide>
        <Carousel.Slide>2</Carousel.Slide>
        <Carousel.Slide>3</Carousel.Slide>
        {/* ...other slides */}
      </Carousel>
    </div>
  );
}

RangeSlider restrictToMarks

RangeSlider component now supports restrictToMarks prop:

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

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

      <RangeSlider
        restrictToMarks
        defaultValue={[5, 15]}
        marks={[
          { value: 5 },
          { value: 15 },
          { value: 25 },
          { value: 35 },
          { value: 70 },
          { value: 80 },
          { value: 90 },
        ]}
      />
    </Stack>
  );
}

Pagination withPages prop

Pagination component now supports withPages prop which allows hiding pages
controls and displaying only previous and next buttons:

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

const limit = 10;
const total = 145;
const totalPages = Math.ceil(total / limit);

function Demo() {
  const [page, setPage] = useState(1);
  const message = `Showing ${limit * (page - 1) + 1} – ${Math.min(total, limit * page)} of ${total}`;

  return (
    <Group justify="flex-end">
      <Text size="sm">{message}</Text>
      <Pagination total={totalPages} value={page} onChange={setPage} />
    </Group>
  );
}

useForm touchTrigger option

use-form hook now supports touchTrigger option that allows customizing events that change touched state.
It accepts two options:

change (default) – field will be considered touched when its value changes or it has been focused
focus – field will be considered touched only when it has been focused

Example of using focus trigger:

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

const form = useForm({
  mode: 'uncontrolled',
  initialValues: { a: 1 },
  touchTrigger: 'focus',
});

form.isTouched('a'); // -> false
form.setFieldValue('a', 2);
form.isTouched('a'); // -> false

// onFocus is called automatically when the user focuses the field
form.getInputProps('a').onFocus();
form.isTouched('a'); // -> true
