Dynamically adding child components in Editor

Is it possible to have component, that would dynamically add other components as children?

For example:

{“alt”:“Click image for larger version Name: Untitled.png Views: 0 Size: 11.0 KB ID: 1765701”,“data-align”:“none”,“data-attachmentid”:“1765701”,“data-size”:“full”};base64

Adding CustomComponent would add three StaticMeshComponents.

Your attached image is not showing. But to add a component in C++ :

in class constructor:

USceneComponent* SceneComp = CreateDefaultSubobject<USceneComponent>(TEXT("SceneComp"));

and dynamically:

UStaticMeshComponent* Mesh = NewObject<UStaticMeshComponent>(this);

if (Mesh)

Thanks for reply. That seems to be working, but if I am not sure how to properly attach components together.

In header file (WallComponent.h) I create property

UPROPERTY(EditAnywhere, BlueprintReadOnly, Category = Test)
UInstancedStaticMeshComponent* _instances;

and in constructor:

auto name = this->GetName();
name += FString("-wall");

_instances = CreateDefaultSubobject<UInstancedStaticMeshComponent>(*name);

After adding component Wall to Actor in editor I can see that InstancedStaticMeshComponent was attached to Actor and I can edit it using blueprints.
BUT in Details window of attached Wall, there is editable property **Instances **(of type InstancedStaticMeshComponent), which seems to be different one than the attached component.

Any idea what might be cause?

I am afraid this might lead to memory leaks.
