How to break the row with grid in tailwind

Question

I use Tailwind CSS, I attach an image of my project. Here I try to break the row. I explain I would like that whatever the size of the cards of the first row, those of the second row comes to be put directly below. If I understood correctly I have to assign classes to the children but the children are from a database and so they all have the same model component. I tried the row-auto class, but it doesn't work.
