AnyLink Drop Down Menu animation

AnyLink Drop Down Menu
http://www.dynamicdrive.com/dynamici...pmenuindex.htm

I am able to get this menu to work but i have need to customize it a little and i have been trying to figure out but i haven't been able to get it to work yet.

What i want is when the menu opens, it does a fade or a scroll to open. likewise when it closes, it fades out or scroll upwards to close.

At first i tried to use mootools for the animation but i couldnt get it to work because i do not know how to use it.

Then i made my own function which decreases the div's size and then does a setTimeout to call itself again until it hits 0. but since the div that is popped up for each of the menu items is the same div, when you leave one of the menu items to go to the other, the second div scrolls shut if the animation isnt complete.

If anyone has any ideas on how to accomplish this or has a better understanding of mootools or anther js framework that would be easier please let me know.

Thanks.

Well, I'm familiar with jQuery, so using that, adding a fade effect to the menu is straightforward. Just replace the original script in the HEAD section with the below instead:

<script type="text/javascript" src="jquery-1.2.2.pack.js"></script>

<script type="text/javascript">

Make sure you've also uploaded the jquery.js file referenced in the above code from jQuery.com or elsewhere.

It works exactly how i wanted it to. Thanks a lot.

I tried this out dd. I was curious to see how you did it, and to see how it looked in IE 7 because I suspected that, as with most fading of text in IE 7, it would lose its anti-aliasing quality, which it did. Otherwise it's a very slick effect!

Whatever shortcomings or kudos on the fade effect goes to jQuery.

And to whoever chooses to use jQuery's (and many, just about all in fact) fading routines for text. This is really an issue/trend with IE and, as it so happens, Opera. I haven't really looked into the logic behind this as far as the developers of these two browsers are concerned. However, since I surf in Opera, and test in IE (and others) - nothing terribly unusual in that, I'm somewhat surprised that this hasn't become a fairly big issue in the script development community where fading elements containing text is concerned.

Very nice.. I incorporated this effect and like the fade in fade out transition. adds a bit of life & sophistication versus just popping on and off like a light switch!

BUT.. as the op asked, could it be made to slide down or slide up on mouse over and mouse out? I have seen some very cool scripts where the menu slides down and then slides back up.

I love this script, have already spent time customizing it for my site, so want to stick with it and see if it can be taken to the next level and slide up and down as a transition?

And no, I am not asking to have both effect in 1 mind you, but given a choice, I would rather have the slide up and down transition than the fade in/out.

I just do not have that level of skill.
