# createGroupTemplate(_:)

Creates a template group which may be used as a prototype for further group instances.

## Declaration

```swift
class func createGroupTemplate(_ children: [AUParameterNode]) -> AUParameterGroup
```

## Parameters

- `children`: The template group’s child nodes.

## Return Value

Return Value A newly-initialized parameter group template.

## Discussion

Discussion Template groups provide a way to construct multiple instances of identical parameter groups, sharing certain immutable state between the instances. Template groups may not appear in trees except at the root.
