What is a select box /dropdown menu?
A select box, may also be viewed as a "dropdown menu".
1. A dropdown menu has a similar function to radio buttons, in that only one option can be chosen.
2. On the other hand a dropdown menu gives the customer the option to not choose a product.
3. Dropdown menus are suitable when there are many different choices.
Another example would be selecting dessert from many possible choices (five or more) including not having dessert at all.
