<div id="react-root"></div>

CSS

body {
  font-family: Helvetica, sans-serif;
}

.container-root {
  border: 1px solid black;
  padding: 5px;
  margin: 5px;
}

Babel + JSX

const {Editor, CharacterMetadata, RichUtils, ContentBlock, genKey, ContentState, EditorState} = Draft;
const { List, Repeat } = Immutable;
class Container extends React.Component {
  constructor(props) {
    super(props);

		const contentBlocksArray = input.map(word => {
    	return new ContentBlock({
        key: genKey(),
        type: 'unordered-list-item',
        characterList: new List(Repeat(CharacterMetadata.create(), word.length)),
        text: word
      });
    });

  	this.state = {
      editorState: EditorState.createWithContent(ContentState.createFromBlockArray(contentBlocksArray))
    };
  }

  _handleChange = (editorState) => {
    this.setState({ editorState });
  }

  render() {
    return (
      <div className="container-root">
        <Editor 
          placeholder="Type"
          editorState={this.state.editorState}
          onChange={this._handleChange}
        />
      </div>
    );
  }
}

ReactDOM.render(<Container />, document.getElementById('react-root'))
