react-horizontal-scrolling-menu

Animate react-horizontal-scrolling-menu scrolling and build right-to-left menus: noPolyfill defaults to true since v8, so transitionDuration (default 500), a custom-easing-function transitionBehavior, and per-call ScrollOptions { duration, boundary } on scrollToItem/scrollNext/scrollPrev are silently ignored unless noPolyfill={false} (string 'smooth' | 'auto' behaviors still reach native scrollIntoView); the RTL prop (only a direction: rtl CSS class) and its limits — never combine RTL with transition props. Load when scroll animation speed/easing has no effect, when customizing transitions, or when building RTL menus.
