Hey there,
When i open my Kirby page on my mobile device, the navigation does not contain subpages but only the top level navigation items. How can i make kirby show submenu items on mobile deives?
Regards,

Are you talking about the starter kit? You need to change the css and/or use javascript to show the submenu. On mobile, the submenu has display:none; On desktop, it is visible on hover which does not work on mobile.
Okay, should i just take another theme oder what would you recommend?
As @texnixe said, you should adapt the theme’s CSS to fit your needs if everything else looks like you want it to look 
but you should use another theme if you find one that you like better …
