Replicate And Adjust Animated Jquery Drop Down Menu

I have an existing drop down menu with a blue background here:

The task is the following:

1) I would like to replicate the drop down style and animation from here:

2) The drop down menu should be bluish or grayish to fit into the theme (instead of the orange one I want to replicate).

3) Also the drop down should be IE compatible (along with Chrome).

4) The menu should handle 3 levels

5) Finish within 1 week or less
