Hi Gyan
Thanks for your questions, I hope I can answer them all as shown below.
1) It is theme menu edit by go to appearance / menu
2) I have alredy tried that, but then I remove the site.
3) The URL is https://julknudsen.dk
It is the menu link julknudsen forside and Kompetencer I like to hide.
As mentioned I have tried the below CSS code:
#header-menu #menu-julknudsen-3 .menu-item-1570 { display: none;}
#header-menu #menu-julknudsen-2 .menu-item-1570 { display: none;}
#header-menu #menu-julknudsen-3 .menu-item-874 { display: none;}
#header-menu #menu-julknudsen-2 .menu-item-874 { display: none;}
But that is not working in IE11.
Looking forward to hearing from you.
Thanks
Best regards
Morten Knudsen
