Hello Lech,

It does do it on the demo.

See this screenshot https://www.dropbox.com/s/rn0389ruzshgc9t/menu-responsive.PNG?dl=0

This is the bootstrap default styles for responsive websites.

If you want to modify the Bootstrap styles you can use the following CSS styles.

@media (min-width:992px) {

I tried this using Firebug and it allowed more space for the logo and menu to be on the same line.
