following code displays drop down menu when mouse product:hover but I want css code for 3 level drop down menu. I am not able to proceed further. I want css and html coding for multilevel drop down menu.

      <head> <title></title>
        <style type="text/css">
        html, body, div, header, footer, aside, nav, article, section   { margin: 0; padding: 0;}
            header, footer, aside, nav, article, section    { display: block; }
            body            { background: #ece9dd; font:12px Helvetica, Arial, sans-serif; line-height: 18px;}
            h2              { color: #333; }
            a               { color: #337810; }
            p               { margin: 0 0 18px; }
            .moveR { float:right }
            .break { clear:both; margin:10px 0px; }

        /*  navigation { */

        .navigation { background:url(images/grads.png) left -57px repeat-x;

Soluzione 

#menu li:hover ul ul, #menu li:hover ul ul ul, #menu li:hover ul ul ul ul{
display:none;
}

#menu li:hover ul, #menu li li:hover ul, #menu li li li:hover ul, #menu li li li li:hover     ul{
display:block;
}

This code is working in my project perfectly

Altri suggerimenti

Though accepted answer is fine, you can abstract menu items (LIs) to shorten the code:

.menuItem:hover > ul {
    display:block
}

And now you have infinite levels of submenus
