# `GSLayer selectedElementsMappings`

*Instance Method*

Structural mappings for the selected elements.

## Declaration

```swift
func selectedElementsMappings() -> [AnyHashable : Any]
```

```objc
- (NSDictionary *) selectedElementsMappings;
```

```python
selectedElementsMappings() -> dict
```

## Discussion

The mappings identify nodes and shapes by position and other elements by stable keys. They can be applied to layers with corresponding content.
