Value List Widget
A value list widget in an App’s user interface
allows a value to be selected from a list. In the Register Workflow as App Wizard’s Choose UI Widget screen, enter each list value in the edit field, and click
to add the value
to the list. The list values should conform to the parameter type used
for the control. For example, only integer values should be added to a
list that will be used to populate an Integer parameter. Duplicate list
entries are not permitted.
The 
and 
buttons
may be used move the selected element up or down in the list. Click 
to remove a list
element and set its value in the edit field.
The ‘List length (use 1 for dropdown)’ field is used to specify the maximum number of elements to be displayed in the value list control. Enter 1 in this field to format the control as a drop-down list.
