添加以下内容就足够了

{
                label: "Product Property Group",
                value: 'property_group'
            }

然后可以创建一个自定义字段，让我们选择产品属性。
接下来，我们必须使这种变化持久化。

Component.override('sw-custom-field-type-entity', {
    computed: {
    entityTypes() {
        const types = this.$super('entityTypes');

        types.push(
            {
                label: 'Product Property Group',
                value: 'property_group'
            }
        );

        return types;
    }
    }
});
