Can I have categories inside other categories?
We've built a ton of knowledge bases for ourselves and others, and in our extensive experience, you can usually get by with just one level of categories. Customers can navigate the flat structure easily, and great search lets them find what they want in seconds.
But once your knowledge base reaches ~ 100 articles, you might wanna add a little more structure. That's when subcategories become useful.
HelpDocs doesn't currently support subcategories, but it's something we're actively working on. We're already beta testing them with a few of our users, and they'll be launching for everyone very soon. 🎉
