## 정의

```typescript
updateSection(idOrIndex: string | number, patch: Partial<FunnelSectionSpec>): Promise<boolean>
```

| 인수 | 타입 | 필수 여부 |
| --- | --- | --- |
| `idOrIndex` | `string \| number` | 필수 |
| `patch` | `Partial<FunnelSectionSpec>` | 필수 |

반환 타입: `Promise<boolean>`. 요소 등록이 끝난 뒤 메서드를 호출하고 Promise 결과를 await로 기다리세요.
