How to close the input field or popup when user clicked on other than event.

Using this we can perform same Methode as in model popup to the array input fields or buttons.

const outsideClickListener = event => {
        const deltaX = event.offsetX - lastMouseDownX;
        const deltaY = event.offsetY - lastMouseDownY;
        const distSq = (deltaX * deltaX) + (deltaY * deltaY);
        const isDrag = distSq > 3;
        const isDragException = isDrag && !lastMouseDownWasOutside;

        if (!element.contains(event.target) && isVisible(element) && !isDragException) { // or use: event.target.closest(selector) === null
          element.style.display = 'none';
          removeClickListener();
          document.removeEventListener('mousedown', mouseDownListener); // Or add this line to removeClickListener()
        }
    }
