C++ - UFunction - Add Click to Expand and Collapse Pins

In the ufunction declare AdvancedDisplay=N

from source you can see AdvancedDisplay = “2” so it shows 2 lines by default, expand the rest.

UFUNCTION(BlueprintCallable, meta=(WorldContext="WorldContextObject", CallableWithoutWorldContext, Keywords = "log", AdvancedDisplay = "2", DevelopmentOnly), Category="Development")
