I want to know how to expand and collapse a navbox template of my own (class="accent"). I'm already getting a hang of putting wikitexts and becoming a skilled wiki editor for Wikipedia and FANDOM. Does this work? ({| class="accent"mw-collapsible mw-collapsed") Is this navbox template type compatible for expanding and collapsing? Or do I have to use a different navbox?
