2- Sorry to say that but there is no option like this in the menu to set as you want. But our theme has a feature in which you can create a mega menu using a static block. In this option, you can create a mega menu using page builder so this will be possible if you create the mega menu using the static block feature. To know how to create a mega menu using static block here is the complete video link for it: https://www.youtube.com/watch?v=f07MBdnFPfk&t=76s
