I recently found from the answers to Thread:562973, that I can make   the                                            box or text collapsible using   mw-collapsed commands. So, I tried it out here. However, it appears that the content isn't centralised, as it would be in a (non-collapsible) Navbox, as here. How may I have the centralising feature, but without compromising the collapsibility?
