我认为最好的方法是创建两个具有父->子关系的块。

子块将是仅在其父块中可用的嵌套块。请注意下面定义的父级。

registerBlockType( \'prefix/childblock\', {
title: __( \'Inner Child Block\' ), 
parent: [\'prefix/parentblock\'],

  attributes:{ ...//the rest of your block code continues

edit: props => {
    const { className } = props;
    return [
        <div className={className}>
            <InnerBlocks
                allowedBlocks={[\'prefix/childblock\']}
            />
        </div>
    ];
},

Here\'s a good post about how to do this in more depth
