Document Editor provides support for protecting the document with CommentsOnly protection. In this protection, user allowed to add or edit comments alone in the document.

Document editor provides an option to protect and unprotect document using enforceProtection and stopProtection API.

The following example code illustrates how to enforce and stop protection in Document editor container.

import * as ReactDOM from 'react-dom';
import * as React from 'react';
import {
  DocumentEditorContainerComponent,
  Toolbar
} from '@syncfusion/ej2-react-documenteditor';

DocumentEditorContainerComponent.Inject(Toolbar);
function App() {
  let container: DocumentEditorContainerComponent;
  React.useEffect(() => {
    EnforceProtection();
    StopProtection();
}, []);
function EnforceProtection(){
  //enforce protection
  container.documentEditor.editor.enforceProtection('123','CommentsOnly');
}
function StopProtection(){
  //stop the document protection
  container.documentEditor.editor.stopProtection('123');
}
    return (
      <div>
      <button onClick={EnforceProtection}>enforceProtection</button>
      <button onClick={StopProtection}>stopProtection</button>
      <DocumentEditorContainerComponent
        id="container"
        ref={(scope) => {
          container = scope;
        }}
        height={'590px'}
        serviceUrl="https://ej2services.syncfusion.com/production/web-services/api/documenteditor/"
        enableToolbar={true}
      />
      </div>

    );
  
}
export default App;
ReactDOM.render(<App />, document.getElementById('root'));

Comment only protection can be enabled in UI by using Restrict Editing pane

  Toolbar,
} from '@syncfusion/ej2-react-documenteditor';

DocumentEditorContainerComponent.Inject(Toolbar);
function App() {
  let mentionData: any = [

    { "Name": "Andrew James", "EmailId": "[e-mail]" },
    { "Name": "Andrew Fuller", "EmailId": "[e-mail]"}
  ];
  let settings =  {showRuler: true, mentionSettings: { dataSource: mentionData, fields: { text: 'Name' }}};
