This UI element is similar to the classical GUI concept of a selection list with simple and multiple selection (list box). A list of text entries is displayed in a box of a fixed size, which if necessary you can scroll through. One or two columns are displayed for the values and possibly one column for symbols is displayed before the value column(s).
In the case of a simple selection, the selected entry is determined by the lead selection of the dataSource. If the user changes the selection, the selectionChangeBehaviour property is adhered to. With multiple selection the selected entries are determined by the dataSource selection only; selectionChangeBehaviour is not considered.

Other properties that can be inherited are defined in the related higher-level classes. The related UI elements are:
Accessibility
To enable the development of accessible applications the property label is checked during the syntax check.
If no label has been set, and no descriptive text has been specified for the appropriate bound context element in the ABAP Dictionary, the property tooltip is checked.
Dynamic Programming
For dynamic programming, the same properties, events and aggregations are available as in the View Designer. But note that the spelling format and use of upper/lower case is different.
