Hi,
I have created a custom Settings page which stores the links to my social media profiles. So the settings page has my LinkedIn url, Facebook url and Twitter url. This allows me to store these values in one place and use them all over the website.
I also created a Custom Post type with Custom fields. I'm in the Meta Box Builder to define the necessary custom fields and I would like to add a custom field that provides a dropdown with the social media profile urls stored in the Settings page, so that an author is able to select one of the social media profiles when he is creating or editing the Custom Post type.
How can I define a Custom Field in the Meta Box builder that pulls those available values from the custom Settings Page?
