import { Toggle } from '@bloklabs/core/tools';

Configuration

Option	Type	Default	Description
`placeholder`	`string`	`"Toggle"`	Placeholder text shown in an empty toggle block.

Save Data

interface ToggleItemData {
  text: string;     // Toggle title HTML content
  isOpen?: boolean; // Whether the toggle is expanded — persisted and restored on reload
}
