Hmm...I assume this is using the same jquery thing that my menu uses?
If so, then you need to download the JS file from the website where it is hosted. You can then modify the various properties included in it, such as speed for the menu expand, etc.
Once you have done this, save it to your local server, and change the path reference to point to its new location.
I guess that is all you need to do. Should just work...
You are looking for these entries...
slideUp(600);this.getPanes().eq(f).slideDown(800,e)}
Make the values whatever you like....
