Menu desplegable CSS

Hola que tal, consegui el codigo de un menu desplegable, el cual muestra submenus de manera horizontal, el problema es que la posicion en la que aparece siempre es hasta el lado izquierdo de la pagina, la cual no puedo, mas bien no se como modificar, intente cambiando margin:auto, left:0, pero no lo logre, alguien sabe que campos debo modificar para poder posicionar el menu en cualquier parte de la pagina? Este es el codigo:

<span class=codigo>
&lt;html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en"&gt;<br />
&lt;head&gt;<br />
&lt;meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" /&gt;<br />
&lt;meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /&gt;<br />
&lt;title&gt; Men? flyout&lt;/title&gt;<br />
<br />
<br />
<br />
&lt;style type="text/css"&gt;<br />
