In RoboHelp 11, information types only work in Microsoft HTML output. In more recent versions of RoboHelp, do information types function in other types of output in addition to Microsoft HTML? I really don't want to use that output type.
Those sound a bit like Conditional Build Tags (CBT) or maybe Dynamic User-centric Content (DUCC) – both are present in WebHelp & HTML5 help
Yes, Information Types still only apply to CHM format. Out of curiosity, why are you asking about them? As I understand them, they were a feature only partially implemented by Microsoft.
