我需要在地图框地图中添加一个可折叠的侧边栏。
我正在使用这个例子：https://www.w3schools.com/howto/howto_js_collapse_sidebar.asp
这是我的 html 文件。它显示它短暂加载，但随后地图在其顶部渲染。
最终，我想开发一个侧边栏，就像您单击Google地图中的功能时弹出的那样。我还没有找到这样的东西，所以如果有人知道解决方案，请告诉我。

</html>首先，将你的地图添加到主div，并将地图 css 设置为 "position：relative;"您的打开按钮也需要是"位置：绝对"，并且在地图上方显示 z 深度为 1。
我为html，body和map css添加了100%的高度，以确保内容拉伸到全高。
希望这有帮助。
