The Meta Box Tabs (MB Tabs) plugin is an extension for the framework. It is designed to declutter the WordPress admin interface by organizing custom fields into a tabbed layout.
This is EXACTLY the same product as distributed by the developer. Sales Page
Organizational Flexibility: Allows developers to group any number of custom fields into specific tabs within a single meta box.
Native WordPress UI: Uses the default WordPress CSS classes to ensure the tabs look seamless and integrated with the admin core.
Wrapper Control: Provides the ability to remove the standard meta box wrapper/border, creating a modern, “seamless” tabbed look.
State Persistence: Supports a tab_remember parameter to save the last active tab, so the user returns to the same view after saving or reloading the page.
To implement tabs via code, you define a tabs array and then assign each field to a tab ID using the tab key.
Dependency: Requires the free Meta Box plugin to be installed and active.
Field Grouping: While it groups fields visually, the underlying data is still stored as individual meta keys (unless used in conjunction with MB Group).
Styling: While it supports Dashicons out of the box, if you use Font Awesome, you must enqueue the Font Awesome CSS yourself in the admin area.
