      ref="blockEditor"
      :blocks="blocks"
      :users="users"
      :enableDragAndDrop="true"
      @blockChanged="onBlockChanged"
    />
  </div>
</template>

<script setup>
import { ref } from 'vue';
import { BlockEditorComponent as EjsBlockeditor, ContentType } from '@syncfusion/ej2-vue-blockeditor';

const blockEditor = ref(null);

const blocks = [
  {
    id: 'heading-1',
    blockType: 'Heading',
    properties: { level: 1 },
    content: [
      { contentType: ContentType.Text, content: 'Welcome to BlockEditor' }
