Setting the Number of Items Visible in a Select List
By Stephen Bucaro
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.
