I am using the Integrity 1 theme, and when hovering a menu item, the class x-active appears. When you move your mouse away, it takes 2-3 seconds for the class to get removed. How do I remove the x-active class right away?
That is by design so that when you accidentally hover outside the sub-menu, it will not be closed. It is technically possible to override it but that would require custom development which falls outside the scope of our support.
