导航菜单用于导航场景。下面的官方示例展示原生用法与状态，属性名保持上游 API。

## 安装与前置条件

```bash
npm install @astryxdesign/core@0.7.1 @astryxdesign/theme-neutral@0.7.1 @stylexjs/stylex@0.19.0
```

需要 React 19+，按顺序导入基础 CSS 和主题，并设置 Theme Provider。参见[开始使用](/resources/astryx/docs/getting-started)。

## 示例与使用方式

- **导航菜单 · 综合展示 1**：首先体验这个示例，再查看代码理解组件的组合方式。

## API 与上游详细参考

优先使用 0.7.1 官方中文说明；上游尚未提供中文的条目保留英文。属性名、类型及默认值保持原生 API，不把示例状态名称当成组件属性。

## Nav Heading Menu

Accessible menu container and items for nav heading popovers. NavHeadingMenu provides role="menu" with keyboard navigation; NavHeadingMenuItem renders individual selectable items. Pass as the menu prop of SideNavHeading or TopNavHeading.

| 属性 | 类型 | 默认值 | 说明 |
|---|---|---|---|
| children * | ReactNode |  | Menu items. |
| size | 'sm' \| 'md' \| 'lg' | 'md' | Controls min-width and item padding. |
| minWidth | number \| string |  | Minimum width override. |
| xstyle | StyleXStyles |  | StyleX styles for layout customization (margins, positioning, sizing). Must be a stylex.create() value, not an inline style object like style={{}}. |
