CMB2 Metatabs Options
CMB2 Metatabs Options is a plugin for developers who use CMB2 to manage metaboxes and fields. CMB2 Metatabs Options makes it easy to create options pages with multiple metaboxes--and optionally including tabs, any of which can also have multiple metaboxes. Attach your option page(s) to any existing Wordpress menu, or add them as a new top-level menu. Can also be used as a stand-alone class to add functionality to your CMB2 installation. Requires CMB2.
Version 12 adds the ability to completely suppress the plugin CSS, even if adding your own; adds the ability to have the plugin check the user's capability before showing them the page (and having a different capability than the menu display if desired), and hopefully fixes a bug with JS and WP nonces when trying to open or close a metabox.
