Menu API
想要学习更多组件属性和 CSS API，可以查阅 React Menu 组件的 API 文档。
导入
import Menu from '@mui/material/Menu';
// 或
import { Menu } from '@mui/material';组件名称
在主题中，名称“MuiMenu”可用于提供默认属性（props），或者样式覆盖属性
Popover 组件的属性也是可用的。
| 名称 | 类型 | 默认值 | 描述 |
|---|---|---|---|
| open* | bool | false | Control the popup` open state. |
| anchorEl | HTML element | func | A HTML element, or a function that returns it. It's used to set the position of the menu. | |
| autoFocus | bool | true | If true (Default) will focus the [role="menu"] if no focusable child is found. Disabled children are not focusable. If you set this prop to false focus will be placed on the parent modal container. This has severe accessibility implications and should only be considered if you manage focus otherwise. |
| children | node | Menu contents, normally MenuItems. | |
| classes | object | Override or extend the styles applied to the component. See CSS API below for more details. | |
| disableAutoFocusItem | bool | false | When opening the menu will not focus the active item but the [role="menu"] unless autoFocus is also set to false. Not using the default means not following WAI-ARIA authoring practices. Please be considerate about possible accessibility implications. |
| MenuListProps | object | {} | Props applied to the MenuList element. |
| onClose | func | Callback fired when the component requests to be closed. Signature: function(event: object, reason: string) => voidevent: The event source of the callback. reason: Can be: "escapeKeyDown", "backdropClick", "tabKeyDown". | |
| PopoverClasses | object | classes prop applied to the Popover element. | |
| sx | Array<func | object | bool> | func | object | The system prop that allows defining system overrides as well as additional CSS styles. See the `sx` page for more details. | |
| transitionDuration | 'auto' | number | { appear?: number, enter?: number, exit?: number } | 'auto' | The length of the transition in ms, or 'auto' |
| TransitionProps | object | {} | Props applied to the transition element. By default, the element is based on this Transition component. |
| variant | 'menu' | 'selectedMenu' | 'selectedMenu' | The variant to use. Use menu to prevent selected items from impacting the initial focus. |
ref 则会被传递到根元素中。继承
尽管上文没有明文记录， Popover 组件 的属性(props) 在组件Menu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 | .MuiMenu-root | Styles applied to the root element. |
| paper | .MuiMenu-paper | Styles applied to the Paper component. |
| list | .MuiMenu-list | Styles applied to the List component via `MenuList`. |
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。
