https://github.com/barisusakli/nodebb-plugin-topic-noindex This is a plugin that does it for topics.
There is no built in way to do it in core. So to do it for categories you would have to fork and extend the above plugin.
Hi, is it possible to change the order of categories (shown on the main page)?
I couldn't find anything
@exodo oh, I tried to drag the names, now realised I needed to drag the image.. Thank you
