Popover API
想要学习更多组件属性和 CSS API，可以查阅 React Popover 组件的 API 文档。
导入
import Popover from '@mui/material/Popover';
// 或
import { Popover } from '@mui/material';组件名称
在主题中，名称“MuiPopover”可用于提供默认属性（props），或者样式覆盖属性
Modal 组件的属性也是可用的。

| anchorOrigin | { horizontal: 'center' | 'left' | 'right' | number, vertical: 'bottom' | 'center' | 'top' | number } | { vertical: 'top', horizontal: 'left', } | This is the point on the anchor where the popover's anchorEl will attach to.

| container | HTML element | func | A HTML element, component instance, or function that returns either. The container will passed to the Modal component.By default, it uses the body of the anchorEl's top-level document object, so it's simply document.body most of the time. | |

ref 则会被传递到根元素中。继承
尽管上文没有明文记录， Modal 组件 的属性(props) 在组件Popover上同样是可用的。 你可以利用这一点来 指向嵌套组件CSS
| 规则名称 | 全局类名 | 描述 |
|---|---|---|
| root | .MuiPopover-root | Styles applied to the root element. |
| paper | .MuiPopover-paper | Styles applied to the Paper component. |
您可以使用组件自定义选项对组件进行个性化：
- 具备 全局类名.
- 在自定义主体中，设定一个规则名称作为组件的
styleOverrides属性的一部分。
