Using the Combo Box control, you can add a versatile item selection interface to customized forms. Combo boxes are like drop-down list boxes, but they also include a built-in text field, allowing the user to input a data element not listed (like a write-in vote). In your combo box's properties, you can add items to the selectable list, and define data associated with each item, and use this data in your application.
Presentation Designer combo boxes also offer configurable tooltips and a default selection (see Selected Index below).
|Data||The items that will appear in the list, and the data associated with each item.
When the end user selects an item or types a value, that item's data or the typed value will be the data associated with this control. For example, if you add three items to a combo box, then map that combo box to a host field, when the end user chooses (or types) an item, the data associated with the chosen item gets sent to that host field when the form is processed.
