How to add dropdown box , with hyperlinks, in Sharepoint 2010 Site

I have placed the dropdown box in my site, but i dont know how to bind each selection (ie url1, url2, etc..) with a new tab or page.

<form> <label><u>S</u>earch Engines</label> <select accesskey="S" onchange=
"goToPage(this.options(this.selectedIndex).value)"> <option selected>Please select one</option>
<option value="http://search.msn.com/">MSN Search</option> <option value=
"http://www.google.com/">Google</option> <option value="http://www.search.com/">Search.com</option>
<option value="http://www.dogpile.com/">Dogpile</option> </select>form> 

I want the user to just pick one option and the page redirect him to the site he chose.

How can this be done, please?
