Is there any way to change the animation of the portfolio display at homepage?

edited February 2018 in Appointment Theme
My client want that every time the user clicks on the arrow of the portfolio display at homepage the next 3 images will be displayed, I attach an image of my current portfolio display for more clarity.

Previously I asked about this issue but the solution you refered to me didn't work
