I am looking to create a dropdown menu. I just have one question. Instead of hovering and the menu droping down, how do i make it to click and stay down unless clicked again?
That’s something you need to do with JavaScript. If you describe how you want this to work, we may be aple to point you to scripts that already exist. Anyhow, I’ll move this to the JS forum. 
Its easy if you can use jQuery:
$(document).ready(function(){
$(‘ul.menu li’).click(function(){
open your menu here…
}, function(){
close your menu here on second click
});
});
