Here's an example of a drop down select menu:
form>
<p align="center"><b>Select a site </b>
<select id="Choice" style="color: #0000FF" size="1" name="mySelect">
<option value="">Select one</option>
<option value="http://altavista.com">AltaVista</option>
<option value="http://www.yahoo.com">Yahoo</option>
<option value="http://www.google.com">Google</option>
</select>
<input type="button" value="Go" onclick="window.open(Choice.options[Choice.selectedIndex].value)">
</p>
</form >
