Description
Blocks adds to Meta Box the creation of custom blocks for the Gutenberg editor, using fields configured within Meta Box itself to control data, options, and content rendered in the block. This module serves developers and teams that need to transform structured metadata into reusable components in the editor, keeping WordPress logic organized and easier to reuse across different content types.
