# group

The category this definition belongs to, or `nil` if uncategorized.

```
var group: String? { get }
```

## Discussion

Group names are coarse categories such as `"math"`, `"texture"`, or
`"geometric"`. For example, `ND_atan2_float` belongs to `"math"`.

Use this property to organize definitions into sections in a node picker
or library browser UI.
