被折叠到高级栏下，要手动打开。一般用在不太常用的属性上面。
示例代码：
UCLASS(Blueprintable, BlueprintType)
class INSIDER_API UMyProperty_Test :public UObject
{
//PropertyFlags: CPF_Edit | CPF_ZeroConstructor | CPF_IsPlainOldData | CPF_NoDestructor | CPF_SimpleDisplay | CPF_HasGetValueTypeHash | CPF_NativeAccessSpecifierPublic
UPROPERTY(EditAnywhere, SimpleDisplay, Category = Display)
int32 MyInt_SimpleDisplay = 123;
//PropertyFlags: CPF_Edit | CPF_ZeroConstructor | CPF_IsPlainOldData | CPF_NoDestructor | CPF_AdvancedDisplay | CPF_HasGetValueTypeHash | CPF_NativeAccessSpecifierPublic
UPROPERTY(EditAnywhere, AdvancedDisplay, Category = Display)
int32 MyInt_AdvancedDisplay = 123;
}
示例效果：
原理：
如果CPF_AdvancedDisplay，bAdvanced =true
void FPropertyNode::InitNode(const FPropertyNodeInitParams& InitParams)
{
// Property is advanced if it is marked advanced or the entire class is advanced and the property not marked as simple
static const FName Name_AdvancedClassDisplay("AdvancedClassDisplay");
bool bAdvanced = Property.IsValid() ? ( Property->HasAnyPropertyFlags(CPF_AdvancedDisplay) || ( !Property->HasAnyPropertyFlags( CPF_SimpleDisplay ) && Property->GetOwnerClass() && Property->GetOwnerClass()->GetBoolMetaData(Name_AdvancedClassDisplay) ) ) : false;
}
