Block Level Locking

Availability

Gutenberg Plugin v11.6 or greater
WordPress 5.9

Overview

Theme/plugin developer can now manage when a block can be moved or deleted after being inserted. This applies to both core and custom blocks. This is done by registering the block with the new lock attribute. It's properties are move and remove that both accept boolean values with true representing locked and false representing unlocked. This attributes is added to all blocks with a default value of undefined

Dev Note

Examples:

Move and Remove locked.

This configuration does not allow the block to be moved or deleted from the block-editor.

"attributes":{
	"lock": {
		"type":"object",
		"default": {
			"move": true,
			"remove": true
		}
	}
}

Move and Remove unlocked

This configuration allows the block to to be moved or deleted from the block-editor. This is the default configuration.

"attributes":{
	"lock": {
		"type":"object",
		"default": {
			"move": false,
			"remove": false
		}
	}
}

Mix and match the settings

The settings can be configured as needed. This example allows moving the block but not deleting it.

"attributes":{
	"lock": {
		"type":"object",
		"default": {
			"move": false,
			"remove": true
		}
	}
}

`false`	can Remove	can Remove	can Remove
`undefined`	can't Remove	can't Remove	can Remove

Interacting with the `lock` attribute.

Because this is an attribute, it is possible to filter the values or change them via controls.

This repository contains the Feature: Block-level Locking block that provides an example of a block that is locked but can be changed via Sidebar controls.

There is also a filter in place to lock any instance of the List block so that is cannot be moved or deleted.
