How to add category to KDE menu?

[Hans <hans.ullrich@loop.de>]

Dear list,

after update from kde4 to kde5 I am missing the category "hamradio" in kde 
menu.

The gui for editing kmenu I cannot add a category, just add submenus to the 
existing categories.

Maybe it is possible to edit the related config directly, but better would be 
an option in the gui for our unexperienced users.

IMO this is a bug and should be fixed. 

If someone know a quick and dirty solution, it would be nice if he could point 
me to the file, I have to look at.

Thanks

Best

Hans
