Variants

Standard checkboxes

Standard checkboxes are the default style for checkboxes. They are optimal for application panels where all visual elements are monochrome in order to direct focus to the content.

<div style="display: flex; justify-content: space-between;">
    <div style="display: flex; flex-direction: column;">
        <h4 class="spectrum-Heading--subtitle1">Default</h4>
        <sp-checkbox>Web component</sp-checkbox>
        <sp-checkbox checked>Web component</sp-checkbox>
        <sp-checkbox indeterminate>Web component</sp-checkbox>
    </div>

    <div style="display: flex; flex-direction: column;">
        <h4 class="spectrum-Heading--subtitle1">Invalid</h4>
        <sp-checkbox invalid>Web component</sp-checkbox>
        <sp-checkbox checked invalid>Web component</sp-checkbox>
        <sp-checkbox indeterminate invalid>Web component</sp-checkbox>
    </div>

    <div style="display: flex; flex-direction: column;">

Emphasized checkboxes

Emphasized checkboxes are a secondary style for checkboxes. The blue color provides a visual prominence that is optimal for forms, settings, lists or grids of assets, etc. where the checkboxes need to be noticed.

<div style="display: flex; justify-content: space-between;">
    <div style="display: flex; flex-direction: column; justify-content: space-between;">
        <h4 class="spectrum-Heading--subtitle1">Default</h4>
        <sp-checkbox emphasized>Web component</sp-checkbox>
        <sp-checkbox emphasized checked>Web component</sp-checkbox>
        <sp-checkbox emphasized indeterminate>Web component</sp-checkbox>
    </div>

    <div style="display: flex; flex-direction: column;">
        <h4 class="spectrum-Heading--subtitle1">Invalid</h4>
        <sp-checkbox emphasized invalid>Web component</sp-checkbox>
        <sp-checkbox emphasized checked invalid>Web component</sp-checkbox>
        <sp-checkbox emphasized indeterminate invalid>Web component</sp-checkbox>
    </div>

    <div style="display: flex; flex-direction: column;">
        <h4 class="spectrum-Heading--subtitle1">Disabled</h4>
        <sp-checkbox emphasized disabled>Web component</sp-checkbox>
        <sp-checkbox emphasized checked disabled>Web component</sp-checkbox>
        <sp-checkbox emphasized indeterminate disabled>Web component</sp-checkbox>
    </div>

Handling events

Event handlers for clicks and other user actions can be registered on an <sp-checkbox> as they would a standard <input type="checkbox"> element.

<sp-checkbox
    id="checkbox-example"
    onclick="spAlert(this, '<sp-radio> clicked!')"
>
    Web component
</sp-checkbox>

Accessibility

Checkboxes are accessible by default, rendered in HTML using the <input type="checkbox"> element. When the checkbox is set as indeterminate or invalid, the appropriate ARIA state attribute will automatically be applied.
