List view manipulation.

If you want to set a blueprint property like a multiple list you can use a bit mask.

UENUM(Meta = (Bitflags, UseEnumValuesAsMaskValuesInEditor = "true"))
enum class EColorBits
{
	ECB_Red UMETA(DisplayName = "Red"),
	ECB_Green UMETA(DisplayName = "Green"),
	ECB_Blue  UMETA(DisplayName = "Blue")
};


	UPROPERTY(EditAnywhere, Meta = (Bitmask, BitmaskEnum = "EColorBits"))
		int32 ColorFlags;
