react-google-maps: multiple info windows opening up - reactjs

Question

This is probably going to be a stupidly simple react question but please bear with me.
I am trying to run a react-google-maps with multiple markers with info windows. Here is the code:
const MapWithADirectionsRenderer = compose(
withProps({
googleMapURL: "https://maps.googleapis.com/maps/api/js?key=AIzaSyDf-yIqxErTkbWzKhLox7nAANnrfDIY190&libraries=geometry,drawing,places",
loadingElement: <div style={{ height: `100%` }} />,
containerElement: <div style={{ height: `800px` }} />,
mapElement: <div style={{ height: `100%` }} />,
}),
withStateHandlers(() => ({
isOpen: false,
}), {
onToggleOpen: ({ isOpen }) => () => ({
isOpen: !isOpen,
})
}),
withScriptjs,
withGoogleMap,
})
)(props =>
<GoogleMap
defaultZoom={13}
defaultCenter={new google.maps.LatLng(42.357064, -71.062577)}
>
<Marker
position={{ lat: 42.3381437, lng: -71.0475773 }}
onClick={props.onToggleOpen}
>
{props.isOpen && <InfoWindow onCloseClick={props.onToggleOpen}>
<h3>South Boston</h3>
</InfoWindow>}
</Marker>
<Marker
position={{ lat: 42.3875968, lng: -71.0994968 }}
onClick={props.onToggleOpen}
>
{props.isOpen && <InfoWindow onCloseClick={props.onToggleOpen}>
<h3>Somervil</h3>
</InfoWindow>}
</Marker>
{props.directions && <DirectionsRenderer directions={props.directions} />}
</GoogleMap>
);
When I click one of the markers, the info windows for all the markers toggle open. How do I just toggle open the info window of the marker I click?

Answer 1

I would suggest to introduce a component:
class MarkerWithInfoWindow extends React.Component {
constructor() {
super();
this.state = {
isOpen: false
}
this.onToggleOpen = this.onToggleOpen.bind(this);
}
onToggleOpen() {
this.setState({
isOpen: !this.state.isOpen
});
}
render() {
return (<Marker
position={this.props.position}
onClick={this.onToggleOpen}>
{this.state.isOpen && <InfoWindow onCloseClick={this.onToggleOpen}>
<h3>{this.props.content}</h3>
</InfoWindow>}
</Marker>)
}
}
to control info window per marker via MarkerWithInfoWindow state:
<GoogleMap
defaultZoom={13}
defaultCenter={new google.maps.LatLng(42.357064, -71.062577)}>
<MarkerWithInfoWindow position={{ lat: 42.3381437, lng: -71.0475773 }} content="South Boston" />
<MarkerWithInfoWindow position={{ lat: 42.3875968, lng: -71.0994968 }} content="Somervil" />
</GoogleMap>
