No prepended permalink structure?

From WordPress Codex, this option equivalent to with_front parameter:

Should the permalink structure be prepended with the front base. (example: if your permalink structure is /blog/, then your links will be: false -> /news/, true -> /blog/news/). Defaults to true.

So if your permalink is %post_name%, this option does nothing. And I don't think WP supports removing CPT's slug from the permalink.

Hi Eddie,

Meta Box does not support removing the CPT slug from the URL. Please refer to this topic https://support.metabox.io/topic/how-to-remove-the-slug-from-the-permalink-of-a-cpt/
