A user in this forums thread wants to create custom listing pages using a page builder like Elementor. However, they note that while Elementor has the ability to "bring dynamic data through", WPJM's custom fields seem to be inaccessible.

Elementor support has advised that everything needs to be set to (‘public’ => true) and has_archive should also be set to true. They cite this documentation:

Elementor support recommended we contact them directly on GitHub to work out compatibility, if this is something we'd like to pick up in the future.
