thanks for this idea. Actually we could add a "shift" variable, and choose it correctly to be at the right position. The advantage is that the user can continue to scroll. The probleme is that if the shift is positive, the user cannot see the element [0] anymore. So, the Idea would be to go at the end of the list, then make the proper negative shift. Do you think it is possible ? Thanks a lot :)

It looks like a bit complicated. How is the "end" of the list managed for example ? Thanks for any help :)
