Using a short circuit evaluation in a functional component (with hooks):
const Filters = () => {
const [options, setOptions] = useState([]);
return (
<div className="row">
{options.length > 0 && (
<div className="col-md-3">
<CustomComponent />
</div>
)}
</div>
)
}
Is there a way to render multiple elements right after an inline if condition?
{options.length > 0 && (
<div className="col-md-3">
<CustomComponent />
</div>
<div className="col-md-3">
<SecondComponent />
</div>
)}
Code above doesn’t work, react throws an error. options array is filled after a promise resolved from useEffect(). That’s why i’ve added this check, to display elements only when a promise resolved.
UPDATED CODE for @wentjun:
return (
{options.length > 0 && (
<div className="row">
<div className="col-md-3">
<CustomComponent />
</div>
</div>
)}
)
This throws a syntax error.

You should wrap the elements in React Fragments. The reason being, React elements are rendered via a single root node element. Wrapping it in Fragments will allow you to group the elements without adding additional nodes.
return (
<div className="row">
{options.length > 0 && (
<>
<div className="col-md-3">
<CustomComponent />
</div>
<div className="col-md-3">
<SecondComponent />
</div>
</>
)}
</div>
)
