Thanks for responding. I wanted to take my time before responding to let you know my findings regarding the subject.
While I would agree that ACF is the way to go normally, i’m currently working on a multisite that requires custom fields across the network. ACF does not support this. CMB does.
Additionally, ACF+options is pay for in pro. I’d rather not have to pay, and CMB+options works well in this instance, and is relatively easy to setup in code.
I have this configuration fully working on several sites now, and it works perfectly.
Hope this helps.
Let me know if anyone has any questions regarding this config.
