The default install of Tikiwiki uses moreneat theme that has ))::(( to expand and collapse the menus. If you would rather have + and - to expand and contract the menus as in this site,

  • Admin -> Sections -> General -> change the theme to tikineat
  • while there, tick 'display menus as folders'
  • Replace fo.gif (for +) and ofo.gif (for -) in your tiki's /img/icons w/ those on this site (or any other similar images) respectively.
