Accordion Menu Issue

Hello everyone,

I’ve been formatting an accordion menu. I managed to get each menu item to open up to show all the content inside…no more and no less…just as I wanted it.

However, in the process the animation or transition of the menu opening has gone a bit askew.

Here is my current css:

[no need to post CSS – it’s all visible on your site]

How can I get the menu back to opening smoothly like this: http://developerdrive.developerdrive.netdna-cdn.com/wp-content/uploads/2013/04/snippet-2.html#item-1

Thanks for reading.
