Specifying list items for combo boxes and list boxes

The List Item Properties dialog box allows you to specify the list items of a combo box or list box control.

Manually defined values. Allows you to explicitly specify each of the list items.

Identifier. A unique identifier for the list item.
Name. The name that appears in the list for this item. The name is a required field.
Default. For a combo box, specifies whether the list item is the default item displayed in the combo box. For a list box, specifies whether the list item is selected by default.
Script. Specifies the R script or Python for Spark script that is generated when the list item is selected.

You can specify any valid R script or Python for Spark script. For multi-line scripts or long scripts, click the ellipsis (...) button and enter your script in the Script Property dialog.

Note: You can add a new list item in the blank line at the bottom of the existing list. Entering any of the properties other than the identifier will generate a unique identifier, which you can keep or modify. You can delete a list item by clicking on the Identifier cell for the item and pressing delete.
