Checkbox

A control element that allows for multiple selections within a set.

You can explore the checkbox component in the following curated examples.

Anatomy

To set up the checkbox correctly, you'll need to understand its anatomy and how we name its parts.

Each part includes a data-part attribute to help identify them in the DOM.

Design impact on the asChild property

The Checkbox.Root element of the checkbox is a label element. This is because the checkbox is a form control and should be associated with a label to provide context and meaning to the user. Otherwise, the HTML and accessibility structure will be invalid.

If you need to use the asChild property, make sure that the label element is the direct child of the Checkbox.Root component.

Examples

Learn how to use the Checkbox component in your project. Let's take a look at the most basic example:

Controlled Checkbox

To create a controlled Checkbox component, manage the state of the checked status using the checked prop and update it when the onCheckedChange event handler is called:

Indeterminate Checkbox

In some cases, you may need a checkbox to represent a state that is neither checked nor unchecked, known as the indeterminate state. This can be achieved by setting the checked prop to indeterminate:

Checkbox Group

Ark provides a Checkbox.Group component to manage a group of checkboxes. The Checkbox.Group component manages the state of the checkboxes and provides a way to access the checked values:

Render Prop Usage

For cases where you need more flexibility in rendering, the Checkbox component offers the use of a render prop. The render prop function gives you access to the checkbox's API, allowing you to customize the checkbox control's rendering:

Using the Field Component

The Field component helps manage form-related state and accessibility attributes of a checkbox. It includes handling ARIA labels, helper text, and error text to ensure proper accessibility.

Using the Root Provider

The RootProvider component provides a context for the checkbox. It accepts the value of the useCheckbox hook. You can leverage it to access the component state and methods from outside the checkbox.

If you're using the RootProvider component, you don't need to use the Root component.
