添加多属性的注意事项
您最多可以为产品创建 100 个多属性。
每个产品最多可以有 3 个选项。产品和产品间的选项可能会有所不同。例如，某个产品可以使用尺寸、颜色和样式，另一个产品则可以使用重量、装饰和材料。
如果要增加多属性和选项限制数量，只能使用 Shopify 应用商店中的第三方应用。
如果您需要销售的产品具有 100 个以上的多属性或超过 3 个选项，那么您可以自定义模板代码以提取订单项目多属性，以便从客户处获取定制需求。
如果您要保存多属性的专门化信息，则可以使用元字段向您的多属性详情页面添加自定义字段。如果您有 Online Store 2.0 模板，例如免费的 Shopify 模板 Dawn，则可以通过使用模板编辑器来添加对您的产品多属性元字段的引用。
拥有 5 万及以上个多属性的商店使用应用或 CSV 文件导入来上传多属性时将受每日频率限制。在达到上限之前，您一天最多可以添加 1,000 个新的多属性。如果您超出此限制，则会出现错误，您需要等待 24 小时才能使用应用或 CSV 文件导入添加多属性。Plus 商店没有此限制。
如果您要为在线商店添加多属性，并选择缺货后继续销售，那么当您的库存数量为零或者负数时，您仍然可以继续销售产品。例如，您的库存为零，但正在使用产品清单作为预购，并希望客户能够购买产品。产品被购买后，您的库存水平将降至零以下。但是，如果您因不想销售已售罄的产品而取消选择此选项，那么客户将无法购买该产品。

Considerations for adding variants
You can create up to 100 variants for a product.
Each product can have up to 3 options. The options can be different from product to product. For example, one product can use size, color, and style, and another product can use weight, finish, and material.
The variant and option limits can only be increased by using a third-party app from the Shopify App Store.
If you need to sell a product that has more than 100 variants or 3 options, then you might be able to customize your theme code to extract line item properties so that you can get custom requirements from your customers.
If you want to save specialized information for your variants, then you can add custom fields to your variant details pages by using metafields. If you have an Online Store 2.0 theme, such as Dawn, the free Shopify theme, then you can add references to your product variant metafields through the theme editor.
Stores with 50,000 or more variants are subject to a daily rate limit for uploading variants by using an app or CSV file import. You can add up to 1,000 new variants in a day before the limit is reached. If you exceed this limit, then an error is displayed and you need to wait 24 hours before you can add variants by using an app or CSV file import. Plus stores are exempt from this limit.
If you're adding a variant for the online store and you select Continue selling when out of stock, then you can continue selling products when your inventory reaches zero and below. For example, you have zero stock but are using a product listing as a pre-order and want customers to be able to buy the product. As the product is purchased, your stock levels will drop below zero. However, if you deselect this option because you don't want to sell a product that has sold out, then customers can't buy the product.
Add variants while you're creating a product
If you're in the process of creating a product, you can add its variants at the same time.
