A Comprehensive Guide to Designing Intuitive Context Menus (lnkd.in/eVbyTUhU), with helpful guidelines from alignment and repositioning to keyboard navigation, content overflow and safe triangle area. Written by @Michaël Villar. #ux#design
Personally, if I had a choice, I would always, always, always start designing with a click-menu instead of a hover menu. Hover menus delays will be too fast for some users, too slow for others; the UI can feel confusing and frustrating, and unresponsive.
The "safe" triangle assumes a particular movement, which might be true in many cases, but will fail in some other cases. Keeping the submenu open on "click" seems to be more bulletproof, albeit slower in navigation.
