The navigation menu closes immediately upon moving the mouse outside of the menu item's area. How can I introduce a delay that will keep it open a second or less to keep visitors from becoming frustrated when trying to navigate to submenu items?
Superfish is a script that will add a delay to the hover action. It is used in a lot of themes, for instance I know it is used in the Thematic Theme. Untested, but I think this is how you'd apply it (based on the docs).
