The above functionality is already built into the <$view> widget: in the documentation (https://tiddlywiki.com/#ViewWidget) it says: *The content of the <$view> widget is displayed if the field or property is missing or empty.* Thus, you would write something like this: <$view field="caption"><$view field="title" /></$view> Note how the outer $view widget has a matching /$view, and the inner $view widget uses the "short form" with the "/>" ending. enjoy, -e -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
