1）所以有一个很好的例子，通过单击复选框来显示标记组，我想通过自定义标记信息窗口来扩展它。下面是此示例中的代码 - 它非常适合切换标记，但具有无样式的信息窗口。我已经对其进行了一些额外的自定义。即，对地图进行样式化并增加响应性，以便在更改浏览器窗口时标记保持居中：

这是 categories.xml 的内容：

ETC...
</markers>
2）我在这里找到了以下非常好的样式信息窗口的工作示例。我只是不知道如何将该代码与上面的 js 代码一起使用。这是此特定示例生成的 javascript。如果有更好的方法可以做到这一点，并且它可以与上面#1 的代码一起使用，我对此完全开放。与此示例使用的 ExpressionEngine CMS 方法没有任何关系。
var options = {
alignBottom: true,
boxClass: "ui-infobox-dark",
boxStyle: {width:'250px'},
closeBoxMargin: "",
closeBoxURL: "white-close-button.png",
disableAutoPan: false,
enableEventPropagation: false,
infoBoxClearance: new google.maps.Size(0, 0),
isHidden: false,
maxWidth: 0,
pane: "floatPane",
pixelOffset: new google.maps.Size(0, 0),
zIndex: null
};
var infowindow = new InfoBox(options);
var obj = map7_markers[index];
map7_windows.push(infowindow);
google.maps.event.addListener(obj, 'click', function(e) {
obj.position = e.latLng;
obj.getPosition = function() {
return e.latLng;
}
for(var i = 0; i < map7_windows.length; i++) {
map7_windows[i].close();
}
infowindow.setPosition(e.latLng);
infowindow.open(map7_map, obj);
});
map7_window = infowindow;
