I tried the “Mega Menu” approach to build a custom menu using dropdowns and noticed that the dropdowns are “glitching” up and down while scrolling. Tested it in Safari, Chrome, Firefox.
See the video:
To reacreate this:
I’ll definitely take a look. Oddly doesn’t look like this happens when it’s just a dropdown on the page. Thanks for sending this my way and have a great day!
Just a little reminder 
this is still present in Beta 4
It’s on the radar friend. Dropdowns have some updates on the horizon. I have a fix coming for them soon where the dropdowns won’t change the height of the page when they are closed. After that we’ll take a look at this most likely after 6.3.0 full launch, and then I’ll finally finish the controls to change the delay at which you need to be hovering over it for. Have a great weekend!
