To run Meta Box Group, your environment must meet the following minimum specs:
WordPress Version: 6.5 or higher (tested up to 6.9.1).
PHP Version: 7.1 or higher.
Core Dependency: Requires the free Meta Box plugin (v5.0+) to be installed and active.
License: GNU GPL v2+.
One of the primary technical advantages of MB Group is its efficient database handling.
Standard Storage: By default, it bunches all sub-field data into one database entry. This reduces the number of rows in the wp_postmeta table, which can significantly improve query performance on sites with heavy metadata usage.
Custom Tables: If integrated with the MB Custom Table extension, you can map group fields to specific columns in a custom SQL table for even faster indexing.
Page Builders: Native compatibility with Oxygen, Elementor, Bricks, and Beaver Builder.
Multilingual: Officially supported by WPML and Polylang.
API Support: Works with the WP REST API via the MB REST API extension, allowing you to pull group data into headless applications.
JS ID Patterns: Avoid ending field IDs with _{number} (e.g., text_12) inside groups, as this pattern is reserved by the plugin’s cloning script and can cause JavaScript conflicts.
WYSIWYG Fields: While supported, WYSIWYG editors inside nested/clonable groups can be resource-heavy; it is recommended to use the “Basic” or “Teeny” mode for smoother performance.
