Allow passing an array of refs to useClickAway

[matthova]

Is your feature request related to a problem? Please describe.
For my use case I have a button that opens a modal. Once the modal is open, I want clicking away to close the modal, but if I click on the modal toggle button, I get two conflicting commands - from the modal useClickAway event and from the button's onClick event.

Describe the solution you'd like
If I could pass an array of refs then I could prevent the behavior described above by passing a ref for the modal as well as the button.

Describe alternatives you've considered
I had tried making the modal toggle button only fire when the modal is closed, however that still ran into a race-condition, even when setting the mouse events to ['mouseup', 'touchend']. Another alternate solution would be to use a setTimeout, however I'd prefer to not use that.

Oh man, I can't tell you the number of times this has happened to me outside of this library! I'll try to fix this weekend, feel the pain!

@blnk-space any luck? I've run into a second instance where this would be nice: I'm using a portal and need to ref the portal as well. May try to timebox a solution tomorrow

For those who are looking for a solution to this problem
You can check if your dropdown is already open and then close it

Example:

Wrong:

const [isDropdownOpen, setIsDropdownOpen] = useState(false);
const ref = useRef();

useClickAway(ref, () => setIsDropdownOpen(false));

<div className="container" ref={ref}>
    <div className="dropdown" />
</div>

Correct:

const [isDropdownOpen, setIsDropdownOpen] = useState(false);
const ref = useRef();

useClickAway(ref, () => isDropdownOpen ? setIsDropdownOpen(false) : null);

<div className="container" ref={ref}>
    <div className="dropdown" />
</div>

I'm facing exactly this problem and it always takes like 3-4 additional internal state checking just to close a modal correctly, especially when I have to move modal to portal.

Really looking forward to the PR.

Many thanks.

I have a similar use case, and for now, I'm using a ref on the element to ignore to work around it.

If the element contains children you'll need to prevent clicks on them, for example using pointer-events: none.

const [isSidebarOpen, setIsSidebarOpen] = useState(false);
const navRef = useRef(null);
const navButtonRef = useRef(null);

useClickAway(navRef, (event) => {
  const clickedNavButton = event.target === navButtonRef.current;

  if (!clickedNavButton) {
    setIsSidebarOpen(false);
  }
});

Hi, everyone. I added this feature to useClickAway (#2593). Waiting review.

@matthova I saw your PR, but I don't understand why it still hasn't merged.
