entrys in 2 rows

sorry the URL has change to: 2021.beamtenberatung.info

so that the entrys like "HOME" are displayed in the first row and so in the same row as "BEAMTE"

"Home" to display it at the bottom row

you are asking 2 different things, one time at the top, one time at the bottom ...
This is a custom css request, not really something related to the Maximenu CK module

you can change the code by this one

Sorry for that confusion!

I have some entrys with 2 rows (f.e. Beamte - Verwaltung Schule) and some entrys only with one row (f.e. Home)
So is it possible to display the entry whos is only in one row to display at the second row so as you see as screen?

please read my answer, I have given you the solution :

you can change the code by this one

and in which field that entry must add?

since the 16 november that I have given you a CSS code, you have not added any code in your page ?
you shall not just ask me "how to", you shall also do it
add this code in your template or in the maximenu styles in the custom css area
