How to use viewItem option

you can try Components styling,

You must use css 'position: absolute' at the top of Components

function Hello() {
	return (
		<div style={{ top: '10px', position: 'absolute' }}>
			<h1 style={{ fontSize: '5rem' }}>hello world</h1>
			<h1 style={{ marginTop: '600px', fontSize: '5rem' }}>
				React-catbow-ScrollView
			</h1>
		</div>
	);
}

function App() {
	const option = {
		videoImageCount: 754,
		imgUrl: './images/004/',
		startNum: 10000,
		extension: '.jpg',
		scrollAreaY: 4970,
		top: 30,
		viewPort: {
			width: '550px',
			height: '550px',
			margin: '100px 100px',
			borderRadius: '9999px',
		},
	};
	return (
		<ScrollView
			option={option}
			viewItem={<Hello />}
		/>
	);
}
