- * Hook for detecting clicks outside an element

- * @param handler - Callback function to run when click outside is detected
- * @returns Ref to attach to the element

- * @example
- * ```typescript
- * function Dropdown() {
- *   const [isOpen, setIsOpen] = useState(false);
- *   const dropdownRef = useClickOutside<HTMLDivElement>(() => {
- *     setIsOpen(false);
- *   });
