How to automatically create one cell per document and fetch image and other fields into it

Hi can someone tell me how this is possible with frappe builder: I want to create a grid that automatically has one cell per item in a list.

I have a custom doctype called models that contains some data fields and an image filed as well as a check field called show_on_website.
Now i want to show each model where show_on_website is true in the grid. I can fetch the list using data script but I don’t know where and how to add a loop that iterates over the list and add cells. Can someone point me in the right direction ? Thank you very much.

ok i found out you can right click an element in the list on the left and hit “reapeat block” which will create a “repeater” element. when you assign a dynamic value to the repeater it behaves like a for loop and duplicates the elements below it in the hierarchy as many times as there are elements in the list that you passed to it.
