Dropdown menu with autoforward?

Does anyone know the code to make a dropdown menu where the selection automaticly forwards to that specific page?

Example: nti.nl/NTinternet

 

Javascript onhover or onclick maybe?

 

I copy and pasted the following code from the source files of that site, but it is not working for me

</select><select name="niveau" onchange="__doPostBack('niveau','')" language="javascript" id="niveau" class="inputhp">
	<option value="Zoek op niveau">Zoek op niveau</option>
	<option value="/NTInternet/Cursussen/">Cursussen</option>
	<option value="/NTInternet/MBO/">MBO</option>
	<option value="/NTInternet/HBO/">HBO</option>
	<option value="/NTInternet/University/">Universitair</option>
