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.

let container: DocumentEditorContainer = new DocumentEditorContainer({
  enableToolbar: true,
  height: '590px',
});
DocumentEditorContainer.Inject(Toolbar);
container.serviceUrl =
  'http://localhost:5000/api/documenteditor/';
container.appendTo('#container');

//enforce protection
container.documentEditor.editor.enforceProtection('123', 'CommentsOnly');

//stop the document protection
container.documentEditor.editor.stopProtection('123');

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

Enable comment only protection

Note: In enforce Protection method, first parameter denotes password and second parameter denotes protection type. Possible values of protection type are NoProtection |ReadOnly |FormFieldsOnly |CommentsOnly. In stop protection method, parameter denotes the password.

Mention Support in comments

Mention support displays a list of items that users can select or tag from the suggested list. To use this feature, type the @ character in the comment box and select or tag the user from the suggestion list.
