A drop-down list is a graphical control element, similar to a list box, that allows the user to choose one value from a list.
When a drop-down list is inactive, it displays a single value.
When activated, it displays a list of values, from which the user may select one.
<h3>Why do we use drop-down?</h3>
Dropdowns do have their advantages.
Because they are standard widgets, users know how to deal with them.
When used in forms and for attribute selection, dropdown boxes prevent users from entering erroneous data, since they only show legal choices.
