Display Submenu in Mobile Menu

[billyben]

Re: Drop down menu
I am having a Problem that is somehow similar, but not. I have a Submenu on the desktop version, but want all the Points to be visible in the mobile version. Can anyone help me out here. This is what i have in my custom CSS right now.

Any help highly appreciated, i am really not familiar with code ;(

Here ist the Website i am talking about: http://new.transit-txt.ch

And the CSS
/submenu/
nav.primary .sub-menu li{
display: block;
position: relative;
}
.sub-menu li {
margin-top: 4px;
}.sub-menu{
padding-top: 30px!important;
opacity: 0;
transition: opacity 200ms ease;
-webkit-transition: opacity 200ms ease;
pointer-events: none;
position: absolute;
}
nav.primary li:hover .sub-menu{
opacity: 1;
pointer-events: auto;
}

Dear @billyben
the mobile menu should automatically take all the menu points from both menus together?

That is not the case?

Best!
