This works well so far, but the invisible buttons can still be clicked.
Is there a way to limit the Input events so that children of the container node only receive input events when they are inside the area of the parent container node ?
Simply set the buttons “disabled” as when you hide tchem.
That only makes sense for buttons that are completely outside the container, buttons that are half in and half out would be very irritating for the user to be disabled or clickable on their invisible part.
