The Meta Box Admin Columns plugin (MB Admin Columns) is a specialized extension for the core Meta Box plugin. It is designed to bridge the gap between back-end data storage and administrative visibility by displaying custom field values directly in the WordPress “All Posts,” “Users,” or “Terms” list tables.

To use MB Admin Columns, your environment must meet the following minimum specifications (as of 2026):
Core Plugin: Requires the Meta Box framework (free) to be installed and active.
WordPress Version: 6.5 or higher (optimized for current block editor and admin UI standards).
PHP Version: 7.1 or higher (PHP 8.x recommended for performance).
License: GNU GPL v2+.
The plugin allows you to transform the standard WordPress admin list into a data-rich dashboard.
Placement: Insert columns before, after, or replace any existing default WordPress column (like Title, Date, or Author).
Custom Labels: Override the default field name with a custom column title.
Styling: Automatically inherits WordPress admin styles to ensure a native look and feel.
Sorting: Enables sorting for custom field columns. Supports both alphanumeric and numeric sorting logic.
Searchable: Allows the WordPress admin search bar to query data stored within your custom meta boxes.
Filtering: Specifically useful for taxonomy fields; it adds a dropdown filter to the top of the post list.
Standard Fields: Supports all basic field types (Text, Number, Select, Checkbox, Radio, etc.).
Advanced Fields: Supports complex fields like Date, Image, File, oEmbed, and Color.
Object Relationships: Works with Post, User, and Taxonomy fields to show linked data.
You can configure admin columns through two primary methods:
If you use the Meta Box Builder (the drag-and-drop UI), you can enable columns by checking the “Admin Column” box within each field’s settings.
For developers, columns are registered within the $meta_boxes array using the admin_columns key.
Custom Tables: Fully compatible with the MB Custom Table extension. This allows you to display data in admin columns even if it’s stored in separate, non-standard database tables for better performance.
Term & User Meta: Works with MB Term Meta and MB User Meta to display columns on the category/tag list and user list pages respectively.
Admin Columns Pro Integration: There is a separate “Integrator” extension if you prefer using the third-party Admin Columns Pro plugin for even more advanced drag-and-drop layouts.
