React 16 Note

After React 16, you won't access popup element's ref in parent component's componentDidMount, which means following code won't work.

class App extends React.Component {
  componentDidMount() {
    this.input.focus(); // error, this.input is undefined.
  }

  render() {
    return (
      <Trigger
        action={['click']}
        popup={<div><input ref={node => this.input = node} type="text" /></div>}
      >
        <button>click</button>
      </Trigger>
    )
  }
}

Consider wrap your popup element to a separate component:

class InputPopup extends React.Component {
  componentDidMount() {
    this.props.onMount();
  }

  render() {
    return (
      <div>
        <input ref={this.props.inputRef} type="text" />
      </div>
    );
  }
}

class App extends React.Component {
  handlePopupMount() {
    this.input.focus(); // error, this.input is undefined.
  }

  render() {
    return (
      <Trigger
        action={['click']}
        popup={<InputPopup inputRef={node => this.input = node} onMount={this.handlePopupMount} />}
      >
        <button>click</button>
      </Trigger>
    )
  }
}
