Since my uncategorized topics page is still accessible by URL by ordinary users (it’s now a totally blank page), if I could just remove the Uncategorized link from the hamburger menu I wouldn’t have random users clicking there and getting that blank page. So far the CSS solutions I’ve found have not worked. I’d be fine with removing ALL the category links from the hamburger menu, actually. Obviously, I’ve checked this both from a staff and ordinary user account, and have unchecked the “permit uncategorized posts” setting. Thanks!
To remove only the uncategorized category
.hamburger-panel .category-links .category-uncategorized { display: none; }
To remove all
.hamburger-panel .category-links { display: none; }
.hamburger-panel .panel-body-contents > hr { display: none; }
Works like a charm. Thanks! Will the FAQ (New) eventually timeout on its own?
No, it will not timeout. It will disappear only when the FAQ has been read (scroll all the way down).
Is there a way to start with the above solution to hide all, then specifically display only select categories?

그렇게 했는데도 도움이 되지 않았습니다 
CSS 메뉴에 들어가서 수정해야 할 코드 줄을 찾을 수 없었습니다. 어딘가에 추가해야 하는 걸까요?
맞습니다, 해당 CSS 줄은 현재 존재하지 않습니다. 이를 현재 테마에 추가하거나, 활성 테마에 포함된 테마 컴포넌트에 추가해야 합니다.
