Hi, thank you for the great plugin. But I just need to ask if instead of scrolling through the main category, would it be possible to scroll within the child category instead? For example, I have a mother category named “New” and under it is “Car” and “Clothes”. Instead of scrolling through “New” items, would it be possible to scroll within “Car” only? Thank you very much and I salute you for this plugin ??
