# Creating a Sidebar Menu Modifier Class

## Procedure

1. In `./src`, create a file named `SidebarMenuModifier.ts`

```plaintext
├── package.json
├── src
│   ├── SidebarMenuModifier.ts <----
│   ├── image
│   │   ├── favicon.ico
│   ├── index.html
│   ├── index.scss
│   ├── index.ts
├── tsconfig.json
└── webpack.config.js
```

1. Create the `SidebarMenuModifier` builder class, which receives the NavVis IVION Frontend API as a parameter:

```plaintext
// SidebarMenuModifier.ts
import {ApiInterface} from "@navvis/ivion";

export class SidebarMenuModifier {
  constructor(private ivApi: ApiInterface) {
  }
}
```
