Multiple lines carousel slick?

Question

JavaScript

In the slick slider, using rows: 2, I made a carousel in two rows of 5 elements.
But for example, in some places there are only 2-3 elements in the carousel. And then it turns out all the same two lines.
How to do what if 5 or less elements of the slider were in one line, but if more than 5, then already in two?
