Question: Nested Map objects

Hi,
Nice looking library. great job.

Is it possible to use nested properties, like the BlitzListForm, but where the keys are dynamic but each element is of the same type?

```
{
"name": "Charlie",
"children": {
"alice": { "key": "alice", "name": "Alice", "age": 9 },
"bob" : { "key": "bob", "name": "Bob", "age", 10 }
}
}
```

Thanks
