Slider + cms collection issue

Design help General
1

Hello!
I was trying to create an slider with a cms collection list that could be easily modifiable by the client, and the option to create a new slide everytime you want to add an element (or various) is not an option for the client. So I found this video, and it really works without making it manually. BUT, I can’t add more than one element in each slide. How can I do that?
Anyone has a solution for that?

Slider is placed in Col·laboradors Section

Thanks!
