## cloneElement
You'll sometimes use React's `cloneElement` to provide additonal attributes to a child component - i.e, to add an event handler, className, etc. You can achieve similar behaviour in SwiftUI.
### React
```jsx
import React from "react";
export function PageElement() {
return (
<div>
<LayoutElement>
<span>This is the page content</span>
</LayoutElement>
</div>
);
}
export function LayoutElement({ children }) {
return (
<div>
<span>This is the layout</span>
{React.cloneElement(children, {
style: {
fontWeight: "bold",
fontSize: "2rem"
}
})}
</div>
);
}
```
### Swift
```swift
import SwiftUI
struct PageElement : View {
var body: some View {
LayoutElement() {
Text("This is the page content")
}
}
}
struct LayoutElement : View {
var content: () -> Text
var body: some View {
VStack {
Text("This is the layout")
content()
.bold()
.font(.largeTitle)
}
}
}
```
