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>
        );
    }
}
