# Multiline hidden text with align environment [duplicate]

Is there a way to use >! for hidden lines with the \begin{align*} ... \end{align*} environment? I can't seem to get it to work. Any workarounds?

• No idea how one could do that. Don't know if that's even possible. Apr 27, 2016 at 19:11

• @quid, what's your reasoning? (I'm not necessarily disagreeing, just wondering.) Apr 27, 2016 at 19:19
• It makes it more inconvenient to get access to information. This is counter the purpose of the site.
