For general installation and configuration take a look at the react-core-components package.
// App.tsx
import { DBSelect } from "@db-ux/react-core-components";
const App = () => (
<DBSelect>
<option value="test1">Test1</option>
<option value="test2">Test2</option>
<option value="test3">Test3</option>
<option value="test4">Test4</option>
<option value="test5">Test5</option>
</DBSelect>
);
export default App;
