Flash Counter is a dynamic and visually engaging fragment for Liferay DXP that helps create urgency and boost conversions during flash sales by displaying a real-time countdown timer with days, hours, minutes, and seconds. It is fully configurable without code, allowing users to set sale labels, subtitles, discount badges, CTA buttons, and end date/time, while also providing a smart default 24-hour countdown if no date is set. The fragment includes engaging features like flip animations, a live pulsing indicator, multiple themes (Dark, Light, Fire, Ice), flexible layouts, and an automatic Urgency Mode that activates when less than one hour remains. It also handles expiry by showing a custom message or hiding the component entirely, making it a flexible, reusable, and conversion-focused solution for marketing campaigns and e-commerce promotions on Liferay Marketplace.
