Custom Menu PHP Include

[lakaroth]

Yeah i know a little bit how to use developer tool, i know a little bit HMTL and CSS i need a developer for my buisness i also have post in off topic.... because i'm a designer not a developer
I'm glad for all of your answer guys and i say thanks to all of you for your time.

But untill i find a developer who work with me i need to do alone my stuff...

Maybe is better if i try to explain wich result i want for this project.

In this website it works like i want.
http://www.getsimplethemes.com/ (Main website)
http://www.getsimplethemes.com/demos?theme=cleansmart (Live demo)

As you can see, the live demo page is divide by on the top (Nav Bar) on the content (Live demo)
I need to do the same thing, because in my website must be live demo too, also i prefer use a complex jquery menu instead the standard menù.
So i can use only the CMS features for change contents.... and have a cool menù.

I realize trying this, maybe is more easy that i think.... but i have a lot of CSS conflict with the simple command "php include"

Best regards
