## Details

In the previous example we are using the ADF Language Menu as main menu.
The Language Menu component is able to fetch all the languages from the "app.config.json".
This is how the configuration looks like in the the "app.config.json"

```json
"languages": [
        {
            "key": "en",
            "label": "English"
        },
        {
            "key": "fr",
            "label": "French"
        },
        {
            "key": "it",
            "label": "Italian"
        }
    ]
```
In case no setting is provided, the component shows only the English language.
