The best solution is to apply React Fragments when a wrapper element is required since a React Fragment doesn't render an element to the DOM. In this example, the short syntax is used instead of the full syntax.
import React from "react";
const MyComponent = (props) => {
return (
<>
<li>Grouped list item</li>
<li>Grouped list item</li>
<li>Grouped list item</li>
</>
);

You can't create a React components with the code in this file. It's missing a wrapper element, and the best solution is to apply React Fragments.
import React from "react";
const MyComponent = (props) => {
return (
<li>Ungrouped list item</li>
<li>Ungrouped list item</li>
<li>Ungrouped list item</li>
);
};
