# A select menu, just as with a standard HTML <select> tag, creates a drop
# down menu with a list of options for a user to choose. The select menu
# also includes type-ahead functionality, where a user can type a part or
# all of an option string to filter the list.
#
# This is the simplest form of select menu, with a static list of options
# passed in when defining the element.
