I'm trying to render a URL from a settings page in the menu. The settings page is called Business Info, and the custom field is Application Link. I want the URL entered into this field to be the URL on a Custom Link item in my main nav.
I've tried entering this in as the URL field:
[rwmb_meta id="application_link" object_id="site_option" object_type="setting"]
This ends up being converted to http://[rwmb_meta%20id=application_link%20object_id=site_option%20object_type=setting]
Is there anyway to call a custom field value into this URL field in the standard WordPress Menu editor?
