The drop-down /select list functionality enables you to predefine input values for portlet input parameters. When a portlet requires that a user enter a value before receiving a result, the user can select one of several predefined values from a drop-down list.
There are four types of portlet input fields that you can convert to drop-down lists—text fields, password, select lists, and text area.
