AbstractDropDownByIndex Properties
Properties in View Designer
● deselectable
If the value is 'true', the dropdown list has an additional empty element in position one. If you select this entry, the lead selection of the 'texts' node is reset. In this case, the index parameter of onSelect-Events is IF_WD_CONTEXT_NODE=>NO_SELECTION.
There is a system example in the DEMO_UI_STD_SELECTION component (in the DEMO_UI_DROPDOWN_BY_IDX application).
● selectionChangeBehaviour
Enables the application itself to change the lead selection. When you choose an entry in the dropdown list box the lead selection changes. Data may get lost if there is a single node beneath the lead selection.
