Question about the Menu Control

### Description

Dear,

I have a Menu as
```

```

This is working fine until the monitor is set to Portrait and not all items are visible.

I want to improve this behavior by changing the template and put inside a Border with SnapDevicePixels or inside a custom ScrollViewer with left and right arrows visible at the correct time.

Do you know how it's possible to achieve it ?

Regards
