With a list box, you can select from a set of values presented in a list that is always visible. With a single-selection list box, users select one item from a list of mutually exclusive values. With a multiple-selection list box, users select zero or more items from a list of values.
List boxes support locate as you type i.e. when the drop down list has focus and you start typing the item with a name beginning with those letters will be selected.
