Props
Each prop is described in detail below, but for a quicker reference - check out the propTypes object in src.

<ScrollIntoViewIfNeeded options={{
scrollMode: 'always',
}}>

The active prop allows controll of when to scroll to the component. By default, it will attempt to scroll as soon as it is mounted, but you can set this prop to manually control when to trigger the scroll behavior from the parent component.

constructor(props) {
super(props);
this.state = { active: false };
}
handleScrollToggle = () => this.setState({ active: !this.state.active });
render() {
const { active } = this.state;
return (
<div>
<button onClick={this.handleScrollToggle}>Scroll</button>
<div style={{ paddingTop: 2000 }}>
<ScrollIntoViewIfNeeded active={active}>
<div>Hello</div>
</ScrollIntoViewIfNeeded>
</div>
</div>
);
}
}

className, id, etc
You can also pass normal element attributes like className to the component.
