Display the InfoWindow of all markers by default

[urbannet92]

Hello,
how I can display the InfoWindow of all markers by default.
Thank you.
My code is:

$coord = new LatLng(['lat' => 48.866667, 'lng' => 2.333333]);
// ---------------------------------------------------
$map = new Map([
'center' => $coord,
'zoom' => 14,
]);
// Lets add a marker now
$marker = new Marker([
'position' => $coord,
'title' => 'Titre 1',
]);
// Provide a shared InfoWindow to the marker
$infoWin = new InfoWindow([
'content' => '

This is title

'
]);
// $infoWin->setOptions(new InfoWindowOptions(['visible'=>true]));
$marker->attachInfoWindow($infoWin);
$map->addOverlay($marker);
// ---------------------------------------------------

$coord = new LatLng(['lat' => 48.3175245000, 'lng' => 2.0921782000]);
// Lets add a marker now
$marker = new Marker([
'position' => $coord,
'title' => 'Titre 1',
]);
// Provide a shared InfoWindow to the marker
$infoWin = new InfoWindow([
'content' => '

This is title

'
]);
// $infoWin->setOptions(new InfoWindowOptions(['visible'=>true]));
$marker->attachInfoWindow($infoWin);
$map->addOverlay($marker);
// ---------------------------------------------------

// Display the map -finally :)
echo $map->display();
