# 配置布局

布局配置只有在项目初始化时选择 `dynamic` 模板才有效。

`core/settings.ts` 是布局配置项的默认值，其中 `navPos`、`dir`、`theme` 和预构建选项关联。

```typescript
export interface AppSettings {
  navPos?: 'side' | 'top';
  dir?: 'ltr' | 'rtl';
  theme?: 'light' | 'dark';
  showHeader?: boolean;
  headerPos?: 'fixed' | 'static' | 'above';
  showUserPanel?: boolean;
  sidenavOpened?: boolean;
  sidenavCollapsed?: boolean;
}

export const defaults: AppSettings = {
  navPos: 'side',
  dir: 'ltr',
  theme: 'light',
  showHeader: true,
  headerPos: 'fixed',
  showUserPanel: true,
  sidenavOpened: true,
  sidenavCollapsed: false,
};
```

建议不要改动 `setting.ts`，动态设置页面布局可以使用 `setting.service.ts` 服务中的 `setLayout`。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://nzbin.gitbook.io/ng-matero/zh-1/theming/layout.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
