Hello,
We Really apologize about the Delay in replying to your Support Query!
According to the Issue you have described, we suspect that the Mouse hovers over another Main Menu Item when you are trying to go to the Sub Menu. Please make sure that you move your mouse pointer vertically downwards (and not sideways) to avoid this issue to the Mega Menu and then choose your Item. However, if you would still like to Edit the Delay Time of the Sub/Mega Menu FadeOut Time, then simply find the following code in the js/functions.js File inside the superfish: function() Function Block:
delay: 250,
and the Edit the 250 Value according to your Requirements. This will definitely work fine.
Thanks for your Patience. Do let us know if we can help you with anything else or if you find any further issues with Canvas.
