Reveals an interactive popout menu on hover/focus.

• Use left: 100% to move the popout menu to the right of the parent.
• Use visibility: hidden to hide the popout menu initially, allowing for transitions to be applied (unlike display: none).
• Use the :hover, :focus and :focus-within pseudo-class selectors to apply visibility: visible to the popout menu, displaying it when the parent element is hovered/focused.
