jsx

I am trying to build a react dashboard using Core UI's react template found here . CSS .top-stick { position: sticky !important; position: -webkit-sticky; top: 5rem; overflow-y: auto; height: calc(100vh - 5rem); } JSX <div className="animated fadeIn"> <Row className="app-scrollable-body"> <Col xs="12" sm="4" md="3" className="top-stick"> <Card className="toic"> <CardBody> Lorem ipsum dolor sit amet </CardBody> </Card> </Col> <Col xs="12" sm="8" md="9"> <Card> <CardHeader>Card title</CardHeader> <CardBody> Lorem ipsum dolor sit amet </CardBody> </Card> </Col> </Row> <div className="app-fixed

How can I get it so that I delete the exact note that I chose? class App extends Component { constructor(props) { super(props); this.state = { notes: [], title: "", details: "" } this
