La solution mise en place par Amazon est assez bluffante de pertinence et d'efficacité. Et loin d'être simple, techniquement parlant.

Despite having vertical menu items of very low height, Amazon solves the issue of accidentally activating sibling categories by using a mouse path analysis, that adds an extra-long hover delay if the user moves in a direct line toward any of the sub-categories of the expanded drop-down menu — we’ve here marked the mouse path that triggers the extra hover delay in red.

J'aime quand des gens poussent à ce point les problématiques de User Experience.
