Getting Crazy with Nav & Menu Block

I try to achieve the following Menu


(https://scubadiving4all.com/) made with Kadence

when using the Menu Block, I can get the effect on the Destination submenu (2 level) but can’t get the modal on Tablet and Mobile

When adding the Menu inside a Nav Block, all sublevels are coming at the same time

On the header of https://cwicly.webdev4u.info/ i have “Menu on the left”,Button, “Nav”

What can I do that the menu inside the Nav works the same on the desktop as the stand-alone menu?
