Cascade secondary menu display

Good xicos from Spain, if there are flaws in the message is the fault of the translator, jeje
Tengo a problem, I use the Beautiful Pro Theme template.
I have a sub menu in the section Before Header, and I get links in Cascade (on different lines).
I want to go out in a line only and also want it done more narrow.
What I intended in a thousand ways but I have not given this please I need help
