Guidelines on using hyphenation in interactive design

It's a well established recommendation for publications containing masses of continuous text to use hyphenation.

Are there any ideas or guidelines on how hyphenation should be (not) used on interactive elements of UI or those that do not represent part of text content? For example, when designing 1) a menu 2) sitemap 3) sidebar etc.

The search didn't give me anything on this subject. I think mainly of web interfaces here but it may be interesting how this may be applied to app design too.
