Accepted Answer

Some digging suggests you use the 'attribute' function - see Accessing array values using array key from Twig.

I suppose that would be something like

```
form_widget(attribute(form.orderItems, index).enabled)
```

Unfortunately I can't easily test that at the moment, but it should get you on the right track.
