My issue is I am using Angular 6, Bootstrap v4 and jQuery for the multi-item carousel. If I have data like [1,2,3,4,5,6] there on the carousel it has to show [1,2,3]. After pressing the next it has to show [4,5,6].
Up to this part I achieved, I am facing issues. Only the first active card is moving and there is a lagging also and the previous and next button are not visible. Please check once Stackblitz file you will understand the issue
Here is my work in Stackblitz
