 You can also add user-defined content to menu items via the `params` field. The FixIt theme currently provides two parameters:
 
 * **class** *{String}* add css class to a specific menu item
-* **draft** *{Boolean}* whether set as a draft menu item that will not be rendered in the production environment
+* **draft** *{Boolean}* whether set as a draft menu item whose function is similar to a draft post/page

+{{< admonition >}}
+The draft menu items and posts/pages can be rendered by starting the `Hugo server` command or adding the `-D`/`--buildDrafts` parameter to `hugo` command.
+
+This helps to distinguish the different contents of preview environment and production environment during deployment.

 您还可以通过 `params` 字段将自定义的内容添加到菜单项。 FixIt 主题目前提供了两个参数的配置：
 
 * **class** *{String}* 添加 CSS 类到特定的菜单项
-* **draft** *{Boolean}* 是否为草稿菜单，草稿菜单不会在生产环境渲染
+* **draft** *{Boolean}* 是否为草稿菜单，类似草稿页面

+`hugo server` 命令启动或者为 `hugo` 添加 `-D`/`--buildDrafts` 参数，都能渲染草稿菜单和页面。
+
+这样做有利于在部署时很好地区分**预览环境**和**生产环境**不同的内容。
