M1hono you can create a new category and check the box to treat it as a section.

julian I was aware of this feature, but its effect is far from satisfying the requirements. As I mentioned, I am looking for a way to have multiple sections to organize all Categories. I came across a plugin that implemented this feature, but the plugin notes that most current NodeBB themes have already incorporated this. However, from what I've observed, only the Vanilla theme truly implements multiple sections, while others, especially Persona, render the sections unclickable. The display of Categories and sub-forums is just normal, and it's even less justifiable to use them as classified sections.
