Use Hoverintent delay

Problem/Motivation

The HoverIntent feature does not appear to work. Mouseover the menu immediately causes the menu to appear, however quick the mouseover. This causes UX issues when dragging across the menu on the way to a target on the other side of it. The menu appears, often obscuring the target you were trying to click on.

Steps to reproduce

Move the cursor across the megamenu on the way to a target link. The menu appears when not desired.

Proposed resolution

Add a hoverIntent timeout before showing the menu

Make HoverIntent Timeout a UI option
