Oracle APEX - Setting Null Display Value for POPUP LOVs

Question

I have a few select list boxes on my page and when nothing is selected, I want the value to be shown as Select a Value. So I set Null Display Value property to Select a Value. That works fine for select lists that are using either a shared list or a SQL query as its source, but not for those that use Popup LOV as its source. How can I set null display value for Popup LOVs?

Answer 1

Put "Select a Value" into the Value Placeholder Popup LOV item's property.
