Wikipedia template use own class "collabsible". Wikia use "mw-collapsible" with additional classes "mw-collapsed" (add collapsing by default), "mw-customtoggle-id", "mw-customcollapsible-id" (for toogle and collapsible element). Help:Collapsing TableWiz fix template already. However, you can choose any option.
