i want it to look like this but i cant get it to work it all messes up :/ Could someone guide me or help me do it?

First of all, I don't want anyone to think this is a request forum. It is not! This forum, & the whole coding section is for getting code support. I repeat: Not a request section!

And, about this dropdown.. I'm so very very bored of it. Why not pick another one?

I need your board link to provide any further assistance.
I need your board link ^^

Add the CSS to your stylesheet.
Create a HTML page with the jQuery, so you can create an external javascript file.
Place the external javascript file and the HTML were you want the navigation.

But as Saxaca says, try some more unique - and pleace give us a board link (:
