LoadingOverlay | Mantine

Usage

LoadingOverlay renders an overlay with a loader over the parent element with relative position. It is usually used to indicate the loading state of forms. Note that elements under the overlay are still focusable with the keyboard, so remember to add additional logic to handle this case.

The LoadingOverlay rendering is controlled by the visible prop:

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

function Demo() {
  const [visible, { toggle }] = useDisclosure(false);

  // Note that position: relative is required
  return (
    <>
      <Box pos="relative">
        <LoadingOverlay visible={visible} zIndex={1000} overlayProps={{ radius: "sm", blur: 2 }} />
        {/* ...other content */}
      </Box>

      <Group justify="center">
        <Button onClick={toggle}>Toggle overlay</Button>
      </Group>
    </>
  );
}

Loader props

You can pass props down to the Loader component with loaderProps:

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

function Demo() {
  const [visible, { toggle }] = useDisclosure(true);

  // Note that position: relative is required
  return (
    <>
      <Box pos="relative">
        <LoadingOverlay
          visible={visible}
          zIndex={1000}
          overlayProps={{ radius: 'sm', blur: 2 }}
          loaderProps={{ color: 'pink', type: 'bars' }}
        />
        {/* ...other content */}
      </Box>

      <Group justify="center">
        <Button onClick={toggle}>Toggle overlay</Button>
      </Group>
    </>
  );
}

Custom inline loaders

To replace the default loader with any custom content, set loaderProps={{ children: <div>Your content</div> }}. You can put any React node inside loaderProps.children:

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

function Demo() {
  const [visible, { toggle }] = useDisclosure(false);

  return (
    <>
      <Box pos="relative">
        <LoadingOverlay visible={visible} loaderProps={{ children: 'Loading...' }} />
        {/* ...other content */}
      </Box>

      <Group justify="center">
        <Button onClick={toggle}>Toggle overlay</Button>
      </Group>
    </>
  );
}
