Take, for instance, a commonly included input in checkout forms, the “Country Selection” drop-down.

Why should you avoid drop-down menus on navigation?

Drop-downs can sometimes render a website unusable on an iPhone or Blackberry and can also make life difficult on iPads. Drop-down menus can also encourage "navigation creep" in which the website owners keep adding more and more menu options simply because they can.

Under what circumstances would you use a drop-down menu vs a tab menu?

Tabs are good when you have content that is different in each section. Drop downs are good for selecting a variable in one field.
