Editor compatibility

Layer:Block product integration

EditorStatusAssembly and boundaries
ClassicUnsupportedThis entry targets continuous-flow Block, not the paginated Classic product. Use the corresponding shared or Word capability with Classic assembly.
BlockSupportedcreateBlockEditorPreset — The default createBlockEditor preset installs this capability. Configure the corresponding preset child; graphic editing uses the preset's workspace ports, while persistence and assets remain host-owned. Avoid duplicate extensions.

“Supported” means the product assembly above exists; interaction, host services and file formats retain their own conditions. See status and integration rules. Licensing is shown separately.

Installation

sh

Install in Editor extensions. The host supplies a view, container and persistence; see Quick start.

ts

Use compatible versions available from your distribution source. This site uses the Alpha workspace. License labels come from package metadata; see support and licensing.

Integration by editor

These snippets use an existing host element named element. The host owns container sizing and persistence; call instance.destroy() on teardown. Avoid duplicating preset capabilities and supply required host ports before installation.

Configuration

This entry has no independent configuration fields. Set document attributes through domain commands; presets may install other configurable children.

Commands and runtime

These commands are supplied directly by this extension. Availability depends on the installed schema, selection and protection policy; query editor.can() first.

CommandParameter signature
setBlockContainersetBlockContainer(attrs: Partial<BlockContainerAttributes>)
updateBlockContainerupdateBlockContainer(__0: BlockContainerChange)
unwrapBlockContainerunwrapBlockContainer(position: number)

These are parameter signatures. See commands and controls to connect UI while retaining one transaction/history authority.
