Nexths 13 static site generation

hi all experts,

I am new to nextjs react mui development.

I want to create a simple dashboard. There is no server componenets.

I am confused with nextjs 13 documents. I mean app directory is server component. Then it talks about layout inside app directory. Layout is graphical component. What gives?

I used mui button and i have to use "use client" directive.

What i want is this. I just want to create Flat html static site generation for my dashboard. Then i customize some part for dynamic data fetching ( x-datagrid)

Guide me on how to get static site generation for dashboard layout.

thanks much!.
