免费 Shopify 模板的版本 11.0.0 或更高版本中支持快速订单列表分区。如果您想在商店中添加“快速订单列表”分区，则可将商店模板更新为最新版本。

如果您不想更改或更新模板，则可以使用 Liquid 或 Javascript 向您的模板中添加代码，以在产品页面上显示“快速订单列表”分区。

在更新您的模板文件之前，请确保复制您的模板以创建备份副本。

这属于高级教程。如果您不擅长查阅和编辑模板代码，则您可以与开发人员合作或聘请 Shopify 专家。

您可以将代码添加到您模板的以下文件中，以支持“快速订单列表”分区：

main-product.liquid 或等效文件 步骤： 在 Shopify 后台中，转至在线商店 > 模板。 找到要编辑的模板，点击 ... 按钮打开操作菜单，然后点击编辑代码。 打开要编辑的文件。 在文件底部创建新行，然后添加以下代码：

添加 Javascript 快速订单列表代码

当多属性的购物车数量发生变化时，产品小计、多属性小计和可能出现的错误状态将会更新。可以使用 Javascript 代码获取更新后的值。

您可以向 theme.js 文件或等效文件中添加代码。

步骤：

在 Shopify 后台中，转至在线商店 > 模板。 找到要编辑的模板，点击 ... 按钮打开操作菜单，然后点击编辑代码。 打开 theme.js 文件。 在文件底部创建新行，然后添加以下代码：
