# KendoReact Checkbox Overview

The KendoReact Checkbox lets the user toggle between checked, unchecked and the optional indeterminate states.

The Checkbox is designed to replace the `<input type="checkbox">` HTML5 tag and provides the KendoReact specific styling.

The CheckBox is typically used to represent boolean values via a binary checked state. All regular [`input type="checkbox"`](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/checkbox) HTML attributes are applicable.

The KendoReact Checkbox component is part of the KendoReact library of React UI components. It is distributed through NPM under the [kendo-react-inputs package](https://www.npmjs.com/package/@progress/kendo-react-inputs).

The following example demonstrates the Checkbox component in action.

## Border Radius
