Checkbox

<sl-checkbox> | SlCheckbox

Checkboxes allow the user to toggle an option on or off.

Examples

Basic Checkbox

Financial products access
<sl-checkbox>Financial products access</sl-checkbox>
sl-checkbox Financial products access
import SlCheckbox from '@teamshares/shoelace/dist/react/checkbox';

const App = () => <SlCheckbox>Checkbox</SlCheckbox>;

Description

Add descriptive help text to individual checkbox items with the description attribute. For descriptions that contain HTML, use the description slot instead.

Financial products access
<sl-checkbox description="Grants access to cash account and charge card features">Financial products access</sl-checkbox>
sl-checkbox description="Grants access to cash account and charge card features" Financial products access
import SlCheckbox from '@shoelace-style/shoelace/dist/react/checkbox';

const App = () => <SlCheckbox help-text="What should the user know about the switch?">Label</SlCheckbox>;

Contained

Add the contained attribute to draw a card-like container around a checkbox. Add to a Checkbox Group to draw a container around each checkbox in the group. This style is useful for giving more emphasis to a checkbox or list of checkboxes.

Financial products access

<sl-checkbox description="Grants access to cash account and charge card features" contained>Financial products access</sl-checkbox>
<br/>

import { SlCheckbox } from '@teamshares/shoelace/dist/react';
const App = () => (
  <>
    <SlCheckbox contained style="width: 100%;">

    </SlCheckbox>
    <SlCheckbox contained disabled style="width: 100%;">

      Checked
      <div slot="help-text">A short description about this option</div>
    </SlCheckbox>
  </>
);

Selected Content

Use the selected-content slot to display additional content (such as an input field) inside a contained checkbox when it is checked. The slot is unstyled by default. Use ::part(selected-content) to style the content as needed.

Grant financial products access

A mobile number is required to grant this user access to financial products. The number will be used for login verification.

<sl-checkbox style="width:100%" contained>Grant financial products access
  <div slot="selected-content">
    <p>A mobile number is required to grant this user access to financial products. The number will be used for login verification.</p>
    <sl-input style="width: 280px;" label="Mobile number" type="tel" required optional-icon></div>
</sl-checkbox>
<style>
  sl-checkbox::part(selected-content) {
    font-size: 14px;
    font-weight: normal;
    color: #6D7176;
  }
</style>
sl-checkbox style="width:100%" contained="true"
  | Grant financial products access
  div slot="selected-content"
    p A mobile number is required to grant this user access to financial products. The number will be used for login verification.
    sl-input style="width: 280px;" label="Mobile number" type="tel" required="true" optional-icon="true"
css:
    sl-checkbox::part(selected-content) {
    font-size: 14px;
    font-weight: normal;
    color: #6D7176;
  }
import { SlCheckbox } from '@teamshares/shoelace/dist/react';
const App = () => (
  <>
    <SlCheckbox contained style="width: 100%;">
      Checked
    </SlCheckbox>
    <SlCheckbox contained disabled style="width: 100%;">
      Disabled
    </SlCheckbox>
    <SlCheckbox contained checked style="width: 100%;">
      Checked
      <div slot="help-text">A short description about this option</div>
    </SlCheckbox>
  </>
);

Checked

Use the checked attribute to activate the checkbox.

Financial products access
<sl-checkbox checked>Financial products access</sl-checkbox>
sl-checkbox checked="true" Financial products access
import SlCheckbox from '@teamshares/shoelace/dist/react/checkbox';

const App = () => <SlCheckbox checked>Checked</SlCheckbox>;

Indeterminate

Use the indeterminate attribute to make the checkbox indeterminate.

Indeterminate
<sl-checkbox indeterminate>Indeterminate</sl-checkbox>
sl-checkbox indeterminate="true" Indeterminate
import SlCheckbox from '@teamshares/shoelace/dist/react/checkbox';

const App = () => <SlCheckbox indeterminate>Indeterminate</SlCheckbox>;

Disabled

Use the disabled attribute to disable the checkbox.

Disabled
<sl-checkbox disabled>Disabled</sl-checkbox>
sl-checkbox disabled="true" Disabled
import SlCheckbox from '@teamshares/shoelace/dist/react/checkbox';

const App = () => <SlCheckbox disabled>Disabled</SlCheckbox>;

Custom Validity

Use the setCustomValidity() method to set a custom validation message. This will prevent the form from submitting and make the browser display the error message you provide. To clear the error, call this function with an empty string.

Check me
Submit
<form class="custom-validity">
  <sl-checkbox>Check me</sl-checkbox>
  <br />
  <sl-button type="submit" variant="primary" style="margin-top: 1rem;">Submit</sl-button>
</form>
<script>
  const form = document.querySelector('.custom-validity');
  const checkbox = form.querySelector('sl-checkbox');
  const errorMessage = `Do not forget to check me!`;

  // Set initial validity as soon as the element is defined
  customElements.whenDefined('sl-checkbox').then(async () => {
    await checkbox.updateComplete;
    checkbox.setCustomValidity(errorMessage);
  });

  // Update validity on change
  checkbox.addEventListener('sl-change', () => {
    checkbox.setCustomValidity(checkbox.checked ? '' : errorMessage);
  });

  // Handle submit
  form.addEventListener('submit', event => {
    event.preventDefault();
    alert('All fields are valid!');
  });
</script>
form.custom-validity
  sl-checkbox Check me
  br
  sl-button type="submit" variant="primary" style="margin-top: 1rem;" Submit

javascript:
  const form = document.querySelector(.custom-validity);
  const checkbox = form.querySelector(sl-checkbox);
  const errorMessage = `Do not forget to check me!`;

  // Set initial validity as soon as the element is defined
  customElements.whenDefined(sl-checkbox).then(() => {
    checkbox.setCustomValidity(errorMessage);
  });

  // Update validity on change
  checkbox.addEventListener(sl-change, () => {
    checkbox.setCustomValidity(checkbox.checked ?  : errorMessage);
  });

  // Handle submit
  form.addEventListener(submit, event => {
    event.preventDefault();
    alert(All fields are valid!);
  });
import { useEffect, useRef } from 'react';
import SlButton from '@teamshares/shoelace/dist/react/button';
import SlCheckbox from '@teamshares/shoelace/dist/react/checkbox';

const App = () => {
  const checkbox = useRef(null);
  const errorMessage = `Do not forget to check me!`;

  function handleChange() {
    checkbox.current.setCustomValidity(checkbox.current.checked ? '' : errorMessage);
  }

  function handleSubmit(event) {
    event.preventDefault();
    alert('All fields are valid!');
  }

  useEffect(() => {
    checkbox.current.setCustomValidity(errorMessage);
  }, []);

  return (
    <form class="custom-validity" onSubmit={handleSubmit}>
      <SlCheckbox ref={checkbox} onSlChange={handleChange}>
        Check me
      </SlCheckbox>
      <br />
      <SlButton type="submit" variant="primary" style={{ marginTop: '1rem' }}>
        Submit
