Dear @Robertr
Thank you for the Video, helps :)
So there are two ways i can think of doing this at first, However the second may require the aid of a developer if you are not familiar with the basics of CSS or JS/jQuery,

https://laytheme.com/documentation.html#custom-javascript
So the First Option & the simpler but more time consuming:
Would be for each project page find the "slug" or "Class" of the page

and adding Custom CSS in "Lay Options" -"Custom CSS & HTML",

Target the Menu item.
On all projects within "Regie" the menu-item "Regie" remains underlined,
Or on all projects within Kamera the menu-item "Kamera" remains underlined etc
An example of this would be:
body.id-18 .second_menu [data-title~=Regie] span{
border-bottom-width: 2px !important;
}
The Second option would be to use JS/ jQuery:
The Code may ask, What page am i on? or could ask for the permalink structure ,

The Reply would be - Im within "Regie"
And with this 'Answer'
For all pages "regie" matching, make the menu item "regie" underlined
Sorry if this is more complicated than it has to be and if anyone reading this can think of a very obvious solution that i missed
( which can happen often!! ) then please correct me :)
Let me know & best wishes,
Richard
