🧱 Block Item

Places a block when right-clicking on any valid surface.

items:
  default:palm_sapling:
    behavior:
      type: block_item
      block: default:palm_sapling       # Reference an existing block by ID

The block field also accepts an inline block definition — the block is registered under the item's own ID:
