CHOICE LIST is used to provide a list of choices to a User. There are four types of CHOICE LIST:
The type of CHOICE LIST is controlled by the Select Mode: parameter.
The STANDARD type is the default. It appears like a pull-down menu with only the selected item shown in the input box. With a STANDARD CHOICE LIST a User may select only one of the available choices. An example of a STANDARD CHOICE LIST is shown below.
A SINGLE SELECT CHOICE LIST appears differently from the STANDARD type in that more than one of the available choices can be visible inside the input box. However, like STANDARD a User may select only one of the available choices. The figure below shows an example of a SINGLE SELECT CHOICE LIST.
A DISTRIBUTED LIST CHOICE LIST looks just like SINGLE SELECT. However, users can now select multiple non-consecutive choices by holding down either the ‘Shift’ or ‘Ctrl’ key when clicking on their choices.
A SINGLE SELECT RADIO BUTTON CHOICE LIST appears differently from the previous types in that each individual choice is positioned next to a circular radio button. Like the STANDARD and SINGLE SELECT types, a User may select only one of the available choices. The figure below shows an example of a SINGLE SELECT RADIO BUTTON CHOICE LIST using the default orientation of 'Vertical'. The Orientation: parameter can be used to change this orientation to 'Horizontal'.
There are two methods for specifying the choices to be displayed to users in a CHOICE LIST.
Note: Leading and trailing spaces around an item in the comma-separated list in the Choices: parameter are ignored.
Tip: If you link a CHOICE LIST value to an Excel spreadsheet cell using the Range Reference: parameter, you may want to populated the Choices: parameter using a Delimited Object References read from the spreadsheet via a READ EXCEL ACTION.
