CSS DropDown Menu

Question

In the link i provide below, is my first attempt to make a dropdown menu with html and css. The problem is, that in the "Types of Coffee" option that collapses to a drop down menu, the menu does not stay when i try to move the cursor in the links that appear. Any help would be much appeciated!
