Layout Builder Block Copy

Layout Builder Block Copy adds a Copy block action to Drupal's Layout Builder, allowing content editors to duplicate any inline block within the same section with a single click.

Unlike shallow-clone approaches, this module performs a deep clone: each copy becomes a brand-new, fully independent block_content entity. Editing a copied block never affects the original, and deleting the original never removes the copy.

Features

• One-click duplication from the block's contextual menu in Layout Builder edit mode
• Deep cloning — copies are new block_content entities, not references
• Full independence between original and copy in both directions
• Compatible with the Quick Node Clone module — cloned nodes receive their own independent block entities
• No contrib dependencies beyond Drupal core

Requirements

• Drupal 10.3 or higher (Drupal 11 compatible)
• Core Layout Builder module must be enabled
