States in React Check box component

30 Jan 20232 minutes to read

The Essential JS 2 CheckBox contains 3 different states visually, they are:

• Checked
• Unchecked
• Indeterminate

Checked and Unchecked

The CheckBox checked property is used to handle the checked and unchecked state. In checked state a tick mark will be added to the visualization of CheckBox.

Indeterminate

The CheckBox indeterminate state can be set through indeterminate property. CheckBox indeterminate state masks the real value of CheckBox visually. The Checkbox cannot be changed to indeterminate state through the user interface, this state can be achieved only through the property.

app.jsx

import { enableRipple } from '@syncfusion/ej2-base';
import { CheckBoxComponent } from '@syncfusion/ej2-react-buttons';
import * as React from 'react';
import * as ReactDom from 'react-dom';
enableRipple(true);
function App() {
    return (<ul>
          {/* checked state. */}
          <li><CheckBoxComponent label="Checked State" checked={true}/></li>

          {/* unchecked state. */}
          <li><CheckBoxComponent label="Unchecked State"/></li>

          {/* indeterminate state. */}
          <li><CheckBoxComponent label="Indeterminate State" indeterminate={true}/></li>
      </ul>);
}
export default App;
