Hide subcategories without hiding their topics in topic list?

Yeah, there was an issue with how the category was set that I missed locally. I edited the snippet above, and it should work now.

The snippet above allows you to set the categories you want this to work on. If you want it to work on all categories, you’d use something like this.

<script type="text/discourse-plugin" version="0.8">
  const { on } = require("discourse-common/utils/decorators");

  const useParentCategory = function () {
    const parentCategory = this.attrs.topic.category.parentCategory;

    if (parentCategory) {
     this.attrs.topic.set("category", parentCategory);
    }
  };

  api.modifyClass("component:topic-list-item", {
    @on("didReceiveAttrs")
    setCategory() {
      useParentCategory.call(this);
    }
  });

  api.modifyClass("component:latest-topic-list-item", {
    @on("didReceiveAttrs")
    setCategory() {
      useParentCategory.call(this);
    }
  });
</script>
