how can i change number of items in jcarousel in responsive mode
for this purpose you need to open your administration
and go to Configuration
-> All settings
and search for this setting:jcarouselgeneralsettings.responsivebreakpointsforslickslider-pavilion
Edit this setting and change the number after slidesToShow
for each breakpoint.
However, have in mind that this is customization and therefore - it has not been tested. If you encounter any problems with it you would need to deal with them yourself.
