I’m trying to create a pop up subscription box which closes whenever one clicks on the close button or clicks anywhere outside the pop up. I’ve created a modal component and a state showModal which is used to toggle the visibility of this Modal. I have tried to add setShowModal(false) to the outer div element but that just disables the whole modal. What can be done to close the modal whenever we click outside the modal. This is how my main page looks
const [showModal, setShowModal] = useState(false);
return (
<>
<div
className="homepage"
style={{
filter: showModal ? "blur(8px)" : "none",
minHeight:"80vh",
}}
>
<section
className="homepage-hero"
style={{ paddingBottom:"-2rem", minHeight:"100vh" }}
>
<div className="hero-body">
<div className="container">
<div className="columns">
<div className="column ">

Answer
You can use the useOnClickOutside hook. This hook allows you to detect clicks outside of a specified element.
You have to import the followings
Create a ref that we add to the element for which we want to detect outside clicks
const ref = useRef();
State for our modal
const [showModal, setShowModal] = useState(false);
Call hook passing in the ref and a function to call on outside click
useOnClickOutside(ref, () => setShowModal(false));
render here
return(…);
//Hook
import { useEffect } from 'react';
export default function useOnClickOutside(ref, handler) {
useEffect(
() => {
const listener = (event) => {
// Do nothing if clicking ref's element or descendent elements
if (!ref.current || ref.current.contains(event.target)) {
return;
}
handler(event);
};
document.addEventListener("mousedown", listener);
document.addEventListener("touchstart", listener);
return () => {
document.removeEventListener("mousedown", listener);
document.removeEventListener("touchstart", listener);
};
},
// Add ref and handler to effect dependencies
// It's worth noting that because the passed-in handler is a new ...
// ... function on every render that will cause this effect ...
// ... callback/cleanup to run every render. It's not a big deal ...
// ... but to optimize you can wrap handler in useCallback before ...
// ... passing it into this hook.
[ref, handler]
);
