Scaffolding fields

Hi, new to rails but jumpstartrails seems like something i really need for my saas project.

I saw on the youtube video example how the fields are added. But i can’t find a list of all supported fields. Is there a “repeater field” and “image field” (like a repeatable group of child fields) as well? I come from the WordPress world and Advanced Custom fields plugin is a must there.

Any tips also welcome. The saas wil provably be just a data input that will show on the frontend.

Also how should i handle search functions with jumpstartrails?
