我看了，他们使用了一些自定义 JS 代码来强制显示“类别和最新主题”视图。

我没有检查是否有更好的方法；这是他们所做的（我已将代码现代化并添加了一些注释）：

```js
import { apiInitializer } from "discourse/lib/api";
import CategoriesAndLatestTopics from "discourse/components/categories-and-latest-topics";
import CategoryList from "discourse/models/category-list";
import { MAX_UNOPTIMIZED_CATEGORIES } from "discourse/lib/constants";

export default apiInitializer((api) => {
  // 强制显示“类别和最新主题”视图。
  api.modifyClass(
    "component:discovery/categories-display",
    (Superclass) =>
      class extends Superclass {
        get categoriesComponent() {
          if (this.args.parentCategory) {
            return super.categoriesComponent;
          } else {
            return CategoriesAndLatestTopics;
          }
        }
      }
  );

  // 与原始代码相同，只是修改了“this.site.desktopView”检查，
  // 因此它也能为移动设备找到最新主题。
  api.modifyClass(
    "route:discovery-categories",
    (Superclass) =>
      class extends Superclass {
        async findCategories(parentCategory) {
          let model;

          let style = this.siteSettings.desktop_category_page_style;
          if (this.site.categories.length > MAX_UNOPTIMIZED_CATEGORIES) {
            style = "categories_only";
          }

          if (
            style === "categories_and_latest_topics" ||
            style === "categories_and_latest_topics_created_date"
          ) {
            model = await this._findCategoriesAndTopics(
              "latest",
              parentCategory
            );
          } else if (style === "categories_and_top_topics") {
            model = await this._findCategoriesAndTopics(
              "top",
              parentCategory
            );
          } else {
            PreloadStore.remove("topic_list");
            model = await CategoryList.list(this.store, parentCategory);
          }

          return model;
        }
      }
  );
});

```

您可以尝试将代码粘贴到新的组件 → 编辑代码 → JS 选项卡中。  
如果有效，请告诉我。
