Since MediaWiki 1.23/wmf3 has been deployed to all Wikimedia sites, the old script in zhwiki didn't work any more.
The zhwiki's collapsible behavior makes the whole header bar clickable and shows a helpful text indicating the collapse state. Thus, the Navbox and many templates can be easily expand by click the hotspot(header bar) instead of finding the "show/hide" link to click. What do you think of making this behavior as default?
And now, because we want to make use of upstream jQuery.makecollapsible but not break the local collapsible behavior, I think the best way to fix this is adding some configs for jQuery.makecollapsible.
Last, I'd like to see Extension:Scribunto's global module.. Therefore we can unify some common templates globally for unified user experience.
