An HTML Select list is a form control used to create a drop-down list of items from
which the user can select. Each item in a select list is defined by an option element.
The select list can appear as a drop-down list as shown below.
Or, by setting its size property it can appear as a scrolling list, displaying
more than one item at a time. The select list below shows three items because its size
attribute is set to 3.
Note: When setting size to number of items in list, in Gecko-based browsers like Firefox
and Chrome, the scrollbar is grayed out. In Internet Explorer the scrollbar is totally hidden.
