Thank you very much for your reply!
Unfortunately, this doesn’t solve the issue I’m facing.

I have already seen the documentation at https://kriesi.at/documentation/enfold/custom-layout-and-dynamic-content/, but it requires selecting the custom layout manually in the Advanced Layout Builder (ALB) for each post.

What I’m looking for is a way to apply a saved custom layout automatically to newly created posts in a custom post type – in my case, “anzeige”.
These posts are not created in the backend but via a frontend form that fills ACF fields. So I would like the layout to be applied automatically without manual selection in the backend.

Is there a way to assign a specific ALB layout automatically to posts, either via code or some internal Enfold function?

Thank you again for your help!
