Choose from four types of CHOICE LIST in Select Mode:

1. STANDARD
2. SINGLE SELECT
3. DISTRIBUTED LIST
4. SINGLE SELECT RADIO BUTTON

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.

1. Fixed list typed into Choices: parameter as a comma separated list of items.
2. Dynamic list of data extracted from, for example, a database file specified in Choices: parameter as object reference.

Leading and trailing spaces around an item in the comma-separated list in the Choices: parameter are ignored.

If you link a CHOICE LIST value to an Excel spreadsheet cell using in Range Reference:, you may want to use an object reference in Choices: parameter using a read from the spreadsheet via a READ EXCEL ACTION.
