Hi Mohammad, Have a look here: https://tiddlywiki.com/#RevealWidget Especially the retain parameter.
TW has to calculate the condition for both widgets, _but_ the hidden elements are removed from the DOM, by default. So if the content is hidden, It won't cause any performance impact, since the DOM is empty. hope that helps -mario -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
