Meta Box
At its core Meta Box is a modular and very flexible custom fields plugin that is developer friendly. It goes beyond custom fields with 32 extensions. Some of the extensions provide features such as the ability to use a GUI to create Custom Post Types and custom taxonomies, while others provide advanced features such as front-end form submissions and saving fields to a custom table. Meta Box has integrations with Elementor and Beaver Builder. Support for Oxygen is currently being developed. Meta Box includes Meta Box Views, for creating front-end templates, and Meta Box Blocks, for creating Gutenberg blocks for your custom fields. The lifetime bundle is all inclusive and comes with lifetime updates, support, and unlimited sites.
