添加 DOM 属性

添加 DOM 属性

您可以在编辑器内的多个 DOM 元素上设置额外的 HTML 属性。这些元素包括：

editor: 编辑器本身，不包括菜单和工具栏。

block: 块的主容器元素。包含块的内容及其嵌套块。

blockGroup: 编辑器中所有顶级块和嵌套块的包装元素。

blockContent: 块内容的包装元素。

inlineContent: 块富文本内容的包装元素。

在下面的演示中，我们在 block 元素上设置了自定义类，为每个块添加边框：

export default function App() {
  // Creates a new editor instance.

  return <BlockNoteView editor={editor} />;
