|Description|show/hide content of a tiddler while leaving tiddler title visible|

|ELS 3/30/2007: add a shadow definition for CollapsedTemplate.  Tweak ViewTemplate shadow so "fold/unfold" and "focus" toolbar items automatically appear when using default templates.  Remove error check for "CollapsedTemplate" existence, since shadow version will now always work as a fallback. |
|ELS 2/24/2006: added fallback to "CollapsedTemplate" if "WebCollapsedTemplate" is not found |
|ELS 2/6/2006: added check for 'readOnly' flag to use alternative "WebCollapsedTemplate" |
