Hello,
When you go, for exemple, to the main items like “Nuestras colecciones” it will scroll down the menu item but if you try to scroll it up to leave it as before it won’t do it. The same happens with the other main items “Ropa de bebé”, “Accesorios”, “Mi cuenta”. It is weird because with the submenu it works perfectly like for instance: the submenu item “Accesorios para el bebé” you can scroll down and scroll it up again.
