How can this is not supported by default? This is a default on all menus in every theme and also including elementor's menu widget.

This is the one thing we really need. I may have to use our theme's header if this isn't supported. Looking around the web, it seems like something like this menu https://www.twiddy.com/ might work. Where the nested elements are displayed to the right on the desktop and icons etc appear in the menu on mobile.

I need this, or alternatively have what is shown in the additional column change when hovering over menu items

This is a must have :)

This is really needed

Yes, this should be definately be added. The default Elementor menu widget has this included. I use multilevel menu's in lots of projects and the lack of it makes me choose Elementor over Breakdance for some of my projects. Please pretty please add this ;-)

Got examples?

I really really need this.

I was embarassed this is not supporting when I tried to create multi-level menu items. Hope this supporting soon.
