Made with Combobox

Select is an opinionated component built on top of Combobox component. It has a limited set of features to cover only the basic use cases. If you need more advanced features, you can build your own component with Combobox. You can find examples of custom select components on the examples page.

Usage

Select allows capturing user input based on suggestions from the list. Unlike Autocomplete, Select does not allow entering custom values.

Your favorite library

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

function Demo() {
  return (
    <Select
      label="Your favorite library"
      placeholder="Pick value"
      data={['React', 'Angular', 'Vue', 'Svelte']}
    />
  );
}

Controlled

Select value must be a string, other types are not supported. onChange function is called with a string value as a single argument.

import { useState } from 'react';
import { Select } from '@mantine/core';

function Demo() {
  const [value, setValue] = useState<string | null>('');
  return <Select data={[]} value={value} onChange={setValue} />;
}

onChange handler

onChange is called with two arguments:

value - string value of the selected option
option – selected option object

If you prefer object format in state, use second argument of onChange handler:

import { useState } from 'react';
import { ComboboxItem, Select } from '@mantine/core';

function Demo() {
  const [value, setValue] = useState<ComboboxItem | null>(null);
  return (
    <Select
      data={[{ value: 'react', label: 'React library' }]}
      value={value ? value.value : null}
      onChange={(_value, option) => setValue(option)}
    />
  );
}

Clearable

Set clearable prop to display the clear button in the right section. The button is not displayed when:

The component does not have a value
The component is disabled
The component is read only

Your favorite library

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

function Demo() {
  return (
    <Select
      label="Your favorite library"
      placeholder="Pick value"
      data={['React', 'Angular', 'Vue', 'Svelte']}
      defaultValue="React"
      clearable
    />
  );
}

Allow deselect

allowDeselect prop determines whether the value should be deselected when user clicks on the selected option. By default, allowDeselect is true:

Option can NOT be deselected

Option can be deselected

This is default behavior, click 'React' in the dropdown

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

function Demo() {
  return (
    <>
      <Select
        label="Option can NOT be deselected"
        placeholder="Pick value"
        data={['React', 'Angular', 'Vue', 'Svelte']}
        defaultValue="React"
        allowDeselect={false}
      />

      <Select
        label="Option can be deselected"
        description="This is default behavior, click 'React' in the dropdown"
        placeholder="Pick value"
        data={['React', 'Angular', 'Vue', 'Svelte']}
        defaultValue="React"
        allowDeselect
        mt="md"
      />
    </>
  );
}

Searchable

Set searchable prop to allow filtering options by user input:

Your favorite library

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

function Demo() {
  return (
    <Select
      label="Your favorite library"
      placeholder="Pick value"
      data={['React', 'Angular', 'Vue', 'Svelte']}
      searchable
    />
  );
}

Controlled search value

You can control search value with searchValue and onSearchChange props:

import { useState } from 'react';
import { Select } from '@mantine/core';

function Demo() {
  const [searchValue, setSearchValue] = useState('');
  return (
    <Select
      searchable
      searchValue={searchValue}
      onSearchChange={setSearchValue}
      data={[]}
    />
  );
}

Nothing found

Set the nothingFoundMessage prop to display a given message when no options match the search query or there is no data available. If the nothingFoundMessage prop is not set, the Select dropdown will be hidden.

Your favorite library

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

function Demo() {
  return (
    <Select
      label="Your favorite library"
      placeholder="Pick value"
      data={['React', 'Angular', 'Vue', 'Svelte']}
      searchable
      nothingFoundMessage="Nothing found..."
    />
  );
}

Checked option icon

Set checkIconPosition prop to left or right to control position of check icon in active option. To remove the check icon, set withCheckIcon={false}.

Control check icon

With check icon

Check icon position

Left

Right

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

function Demo() {
  return (
    <Select
      checkIconPosition="left"
      data={['React', 'Angular', 'Svelte', 'Vue']}
      dropdownOpened
      pb={150}
      label="Control check icon"
      placeholder="Pick value"
      defaultValue="React"
    />
  );
}

Data formats

Select data prop accepts data in one of the following formats:

Array of strings:

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

function Demo() {
  return <Select data={['React', 'Angular']} />;
}

Array of object with value, label and optional disabled keys:

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

function Demo() {
  return (
    <Select
      data={[
        { value: 'react', label: 'React' },
        { value: 'ng', label: 'Angular' },
      ]}
    />
  );
}

Array of groups with string options:

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

function Demo() {
  return (
    <Select
      data={[
        { group: 'Frontend', items: ['React', 'Angular'] },
        { group: 'Backend', items: ['Express', 'Django'] },
      ]}
    />
  );
}

Array of groups with object options:

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

function Demo() {
  return (
    <Select
      data={[
        { group: 'Frontend', items: [{ value: 'react', label: 'React' }, { value: 'ng', label: 'Angular' }] },
        { group: 'Backend', items: [{ value: 'express', label: 'Express' }, { value: 'django', label: 'Django' }] },
      ]}
    />
  );
}

Options filtering

By default, Select filters options by checking if the option label contains input value. You can change this behavior with filter prop.filter function receives an object with the following properties as a single argument:

options – array of options or options groups, all options are in { value: string; label: string; disabled?: boolean } format
search – current search query
limit – value of limit prop passed to Select

Example of a custom filter function that matches options by words instead of letters sequence:

Your country

import { Select, ComboboxItem, OptionsFilter } from '@mantine/core';

const optionsFilter: OptionsFilter = ({ options, search }) => {
  const splittedSearch = search.toLowerCase().trim().split(' ');
  return (options as ComboboxItem[]).filter((option) => {
    const words = option.label.toLowerCase().trim().split(' ');
    return splittedSearch.every((searchWord) => words.some((word) => word.includes(searchWord)));
  });
};

function Demo() {
  return (
    <Select
      label="Your country"
      placeholder="Pick value"
      data={['Great Britain', 'Russian Federation', 'United States']}
      filter={optionsFilter}
      searchable
    />
  );
}

Sort options

By default, options are sorted by their position in the data array. You can change this behavior with filter function:

Your favorite library

import { Select, ComboboxItem, OptionsFilter } from '@mantine/core';

const optionsFilter: OptionsFilter = ({ options, search }) => {
  const filtered = (options as ComboboxItem[]).filter((option) =>
    option.label.toLowerCase().trim().includes(search.toLowerCase().trim())
  );

  filtered.sort((a, b) => a.label.localeCompare(b.label));
  return filtered;
};

function Demo() {
  return (
    <Select
      label="Your favorite library"
      placeholder="Pick value"
      data={['4 – React', '1 – Angular', '3 – Vue', '2 – Svelte']}
      filter={optionsFilter}
      nothingFoundMessage="Nothing found..."
      searchable
    />
  );
}

Large data sets

The best strategy for large data sets is to limit the number of options that are rendered at the same time. You can do it with limit prop. Note that if you use a custom filter function, you need to implement your own logic to limit the number of options in filter

Example of Select with 100 000 options, 5 options are rendered at the same time:

100 000 options autocomplete

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

const largeData = Array(100_000)
  .fill(0)
  .map((_, index) => `Option ${index}`);

function Demo() {
  return (
    <Select
      label="100 000 options autocomplete"
      placeholder="Use limit to optimize performance"
      limit={5}
      data={largeData}
      searchable
    />
  );
}

renderOption

renderOption callback allows you to customize option rendering. It is called with option object and checked state. The function must return a React node.

Select with renderOption

import {
  IconAlignCenter,
  IconAlignJustified,
  IconAlignLeft,
  IconAlignRight,
  IconCheck,
} from '@tabler/icons-react';
import { Group, Select, SelectProps } from '@mantine/core';

const iconProps = {
  stroke: 1.5,
  color: 'currentColor',
  opacity: 0.6,
  size: 18,
};

const icons: Record<string, React.ReactNode> = {
  left: <IconAlignLeft {...iconProps} />,
  center: <IconAlignCenter {...iconProps} />,
  right: <IconAlignRight {...iconProps} />,
  justify: <IconAlignJustified {...iconProps} />,
};

const renderSelectOption: SelectProps['renderOption'] = ({ option, checked }) => (
  <Group flex="1" gap="xs">
    {icons[option.value]}
    {option.label}
    {checked && <IconCheck style={{ marginInlineStart: 'auto' }} {...iconProps} />}
  </Group>
);

function Demo() {
  return (
    <Select
      label="Select with renderOption"
      placeholder="Select text align"
      data={[
        { value: 'left', label: 'Left' },
        { value: 'center', label: 'Center' },
        { value: 'right', label: 'Right' },
        { value: 'justify', label: 'Justify' },
      ]}
      renderOption={renderSelectOption}
    />
  );
}

Scrollable dropdown

By default, the options list is wrapped with ScrollArea.Autosize. You can control dropdown max-height with maxDropdownHeight prop if you do not change the default settings.

If you want to use native scrollbars, set withScrollArea={false}. Note that in this case, you will need to change dropdown styles with Styles API.

With scroll area (default)

With native scroll

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

const data = Array(100)
  .fill(0)
  .map((_, index) => `Option ${index}`);

function Demo() {
  return (
    <>
      <Select
        label="With scroll area (default)"
        placeholder="Pick value"
        data={data}
        maxDropdownHeight={200}
      />

      <Select
        label="With native scroll"
        placeholder="Pick value"
        data={data}
        withScrollArea={false}
        styles={{ dropdown: { maxHeight: 200, overflowY: 'auto' } }}
        mt="md"
      />
    </>
  );
}

Group options

Your favorite library

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

function Demo() {
  return (
    <Select
      label="Your favorite library"
      placeholder="Pick value"
      data={[
        { group: 'Frontend', items: ['React', 'Angular'] },
        { group: 'Backend', items: ['Express', 'Django'] },
      ]}
    />
  );
}

Disabled options

When option is disabled, it cannot be selected and is ignored in keyboard navigation.

Your favorite library

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

function Demo() {
  return (
    <Select
      label="Your favorite library"
      placeholder="Pick value"
      data={[
        { value: 'react', label: 'React' },
        { value: 'ng', label: 'Angular' },
        { value: 'vue', label: 'Vue', disabled: true },
        { value: 'svelte', label: 'Svelte', disabled: true },
      ]}
    />
  );
}

Combobox props

You can override Combobox props with comboboxProps. It is useful when you need to change some of the props that are not exposed by Select, for example withinPortal:

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

function Demo() {
  return <Select comboboxProps={{ withinPortal: false }} data={[]} />;
}

Change dropdown z-index

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

function Demo() {
  return <Select comboboxProps={{ zIndex: 1000 }} data={[]} />;
}

Inside Popover

To use Select inside popover, you need to set withinPortal: false:

import { Popover, Button, Select } from '@mantine/core';

function Demo() {
  return (
    <Popover width={300} position="bottom" withArrow shadow="md">
      <Popover.Target>
        <Button>Toggle popover</Button>
      </Popover.Target>
      <Popover.Dropdown>
        <Select
          label="Your favorite library"
          placeholder="Pick value"
          data={['React', 'Angular', 'Vue', 'Svelte']}
          comboboxProps={{ withinPortal: false }}
        />
      </Popover.Dropdown>
    </Popover>
  );
}

Control dropdown opened state

You can control dropdown opened state with dropdownOpened prop. Additionally, you can use onDropdownClose and onDropdownOpen to listen to dropdown opened state changes.

Your favorite library

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

function Demo() {
  const [dropdownOpened, { toggle }] = useDisclosure();
  return (
    <>
      <Button onClick={toggle} mb="md">
        Toggle dropdown
      </Button>

      <Select
        label="Your favorite library"
        placeholder="Pick value"
        data={['React', 'Angular', 'Vue', 'Svelte']}
        dropdownOpened={dropdownOpened}
      />
    </>
  );
}

Dropdown position

By default, the dropdown is displayed below the input if there is enough space; otherwise it is displayed above the input. You can change this behavior by setting position and middlewares props, which are passed down to the underlying Popover component.

Example of dropdown that is always displayed above the input:

Your favorite library

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

function Demo() {
  return (
    <Select
      label="Your favorite library"
      placeholder="Pick value"
      data={['React', 'Angular', 'Vue', 'Svelte']}
      comboboxProps={{ position: 'top', middlewares: { flip: false, shift: false } }}
    />
  );
}

Dropdown width

To change dropdown width, set width prop in comboboxProps. By default, dropdown width is equal to the input width.

Your favorite library

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

function Demo() {
  return (
    <Select
      label="Your favorite library"
      placeholder="Pick value"
      data={['React', 'Angular', 'Vue', 'Svelte']}
      comboboxProps={{ width: 200, position: 'bottom-start' }}
    />
  );
}

Dropdown offset

To change dropdown offset, set offset prop in comboboxProps:

Your favorite library

import { Select } from '@mantine/core';
import classes from './Demo.module.css';

function Demo() {
  return (
    <Select
      label="Your favorite library"
      placeholder="Pick value"
      data={['React', 'Angular', 'Vue', 'Svelte']}
      classNames={classes}
      comboboxProps={{ position: 'bottom', middlewares: { flip: false, shift: false }, offset: 0 }}
    />
  );
}

Dropdown animation

By default, dropdown animations are disabled. To enable them, you can set transitionProps, which will be passed down to the underlying Transition component.

Your favorite library

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

function Demo() {
  return (
    <Select
      label="Your favorite library"
      placeholder="Pick value"
      data={['React', 'Angular', 'Vue', 'Svelte']}
      comboboxProps={{ transitionProps: { transition: 'pop', duration: 200 } }}
    />
  );
}

Dropdown padding

Zero padding

10px padding

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

function Demo() {
  return (
    <>
      <Select
        label="Zero padding"
        placeholder="Pick value"
        data={['React', 'Angular', 'Vue', 'Svelte']}
        comboboxProps={{ dropdownPadding: 0 }}
      />
      <Select
        mt="md"
        label="10px padding"
        placeholder="Pick value"
        data={['React', 'Angular', 'Vue', 'Svelte']}
        comboboxProps={{ dropdownPadding: 10 }}
      />
    </>
  );
}

Dropdown shadow

Your favorite library

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

function Demo() {
  return (
    <Select
      label="Your favorite library"
      placeholder="Pick value"
      data={['React', 'Angular', 'Vue', 'Svelte']}
      comboboxProps={{ shadow: 'md' }}
    />
  );
}

Left and right sections

Select supports leftSection and rightSection props. These sections are rendered with absolute position inside the input wrapper. You can use them to display icons, input controls or any other elements.

You can use the following props to control sections styles and content:

rightSection/leftSection – React node to render on the corresponding side of input
rightSectionWidth/leftSectionWidth – controls width of the right section and padding on the corresponding side of the input. By default, it is controlled by component size prop.
rightSectionPointerEvents/leftSectionPointerEvents – controls pointer-events property of the section. If you want to render a non-interactive element, set it to none to pass clicks through to the input.

Your favorite library

import { Select, rem } from '@mantine/core';
import { IconComponents } from '@tabler/icons-react';

function Demo() {
  const icon = <IconComponents style={{ width: rem(16), height: rem(16) }} />;
  return (
    <>
      <Select
        data={['React', 'Angular', 'Vue']}
        leftSectionPointerEvents="none"
        leftSection={icon}
        label="Your favorite library"
        placeholder="Your favorite library"
      />
      <Select
        mt="md"
        data={['React', 'Angular', 'Vue']}
        rightSectionPointerEvents="none"
        rightSection={icon}
        label="Your favorite library"
        placeholder="Your favorite library"
      />
    </>
  );
}

      placeholder="Pick value"
      data={['React', 'Angular', 'Vue', 'Svelte']}
      disabled
    />
  );
}

        placeholder="Boolean error"
        error
        data={['React', 'Angular', 'Vue', 'Svelte']}
      />
      <Select
        mt="md"
        label="With error message"
        placeholder="With error message"
        error="Invalid name"
        data={['React', 'Angular', 'Vue', 'Svelte']}
      />
    </>
  );
}

Styles API

Select supports Styles API, you can add styles to any inner element of the component withclassNames prop. Follow Styles API documentation to learn more.

Select

Description

Component Styles API

Hover over selectors to highlight corresponding elements

/*
 * Hover over selectors to apply outline styles
 *
 */

Get element ref

import { useRef } from 'react';
import { Select } from '@mantine/core';

function Demo() {
  const ref = useRef<HTMLInputElement>(null);
  return <Select ref={ref} />;
}

Accessibility

If Select is used without label prop, it will not be announced properly by screen reader:

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

// Inaccessible input – screen reader will not announce it properly
function Demo() {
  return <Select />;
}

Set aria-label to make the input accessible. In this case label will not be visible, but screen reader will announce it:

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

// Accessible input – it has aria-label
function Demo() {
  return <Select aria-label="My input" />;
}

If label prop is set, input will be accessible it is not required to set aria-label:

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

// Accessible input – it has associated label element
function Demo() {
  return <Select label="My input" />;
}

To set aria-label on the clear button, use clearButtonProps. Note that it is required only when clearable is set.

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

function Demo() {
  return (
    <Select
      data={[]}
      clearable
      clearButtonProps={{
        'aria-label': 'Clear input',
      }}
    />
  );
}
