Simpel CSS dropdown menu

Kære eksperter,

På siden www.fre2011.dk/test.htm ønsker jeg at lave en dropdown menu så når man trykker på competition, kommer der en dropdown menu så at brugeren kan vælge mellem flere øvrige links.

Kan det overhovedet lade sig gøre og hvordan skulle det indsættes i nedenstående CSS?

body {
    margin: 20px 0;
    font-family: verdana, "Trebuchet MS", Arial, Helvetica, sans-serif;
    font-size: 0.75em;
  background: #D9D98C;
  color: #000000;
}

h1 {
}

h2, h3, h4, h5, h6 {
    color: #2582A4;
}

p, ol, ul {
    text-align: justify;
}

strong {
    font-weight: bold;
    color: #808080;
}

a {

}

a:hover {

}

.box {
