Combo Box
A component that combines an editable field and a drop-down list. The user can select a value from the drop-down list. If you make the combo box editable, then the combo box includes an editable field into which the user can type a value. |

This is what a combo box looks like:
The Type of Selected Item property and the type of data in the Value column of the Selection Values tabular property is dynamic. It cannot be manually changed from the GUI Builder, but it is changed by the binding whose target points to the Selection Values property of Combo Box. This binding rewrites the Selection Values table. The binding is automatically created when dragging a field that has selection values to a combo box.
