Newbie attempting to use the Carousel control. The defaults of the control work fine for my needs, but I want to change the number of panels in the control. I only have 3 items that I want to use in the carousel, which are images. However, by default the carousel has 5 or 6 panels. I only want 3 panels for my 3 images in the carousel. How do I change the number of panels in the carousel?
