Sub site "project details" with gallery

Hey Guys,

I am relatively new to Webflow.
I created a site for an architecture office. For the projects-site I want to have a simple list with one picture and a text. By clicking on that picture (or/and heading or whatever) you get to the “project details” with a specific gallery-layout (see picture below), always 10 pics, and another text and infos.

Of course, I’d like to create this as dynamic content.

Can somebody help me to realize it that way?

Here is my public share link (“hard” coded project details"): Projekt 1 - V2
