Overview
This is a field which can be used to make one or more choices from a list. The 'value' property determines what selected option value will be populated in the field when the program gets the screen input. When the program outputs to the screen, the 'value' property should match to an option of the select box; if it does not, the select box will show as empty. Note: for the 'value' to match one of the options of the select box, the formatting of the 'value' and option must also be the same. The list of choices can be loaded in a variety of ways, please see below for more detail.

multiple - This specifies that multiple values can be selected from the select box. The default value of the property is 'false'. If set to 'true' the select box will convert to a List Box.
