I just realised that there is a simple way to do this. You can use the reveal widget. If you have a tiddler where you select the language and have each paragraph wrapped in a reveal widget for that language.
Here is a quick demo: <$radio tiddler='$:/state/Language' field='text' value=English>English</$radio> <$radio tiddler='$:/state/Language' field='text' value=Français>Français</$radio> <$reveal type='match' state='$:/state/Language' text='English'> This is the English text. </$reveal> <$reveal type='match' state='$:/state/Language' text='Français'> Voici le texte français. </$reveal> -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
