How to prevent Properties of EditInlineNew Objects from appearing under Category dropdowns ?

TLDR;

I have this:

but I want this:

Hello,

I have an Array declared with Instanced Specifier:

UPROPERTY(BlueprintReadWrite, EditAnywhere, Instanced, Category = "Config")
TArray<UVisualisationShape*> ShapesToDraw;

…which is meant to store the references to the Objects declared with EditInlineNew Specifier, e.g.

UCLASS(Abstract, DefaultToInstanced, EditInlineNew, ClassGroup = "VisualisationShape",
	meta = (DisplayName = "Visualisation Shape"))
class TLOB_API UVisualisationShape : public UObject
{
	GENERATED_BODY()

public:

	UPROPERTY(EditAnywhere, BlueprintReadWrite)
	FTransform Offset;
	UPROPERTY(EditAnywhere, BlueprintReadWrite)
	FColor Color = FColor::Cyan;
	UPROPERTY(EditAnywhere, BlueprintReadWrite)
	float Thickness = 1.0f;
};

And this works quite well in the Editor.
These Objects appear in the following way when selected:

But there is a small caveat - Properties appear under the dropdowns.

Not a very big deal, but I don’t like it at all.
I wish that these would be listed without expanding any dropdowns.

Is there any way to remove these category dropdowns?
Perhaps, a Specifier for UPROPERTY/UCLASS?
So all the Object’s Properties would appear next to each other (see TLDR section above for image).

Thanks!

Hi!

Have you tried UPROPERTY specifier ShowOnlyInnerProperties?

All UPROPERTY Specifiers

[dzemzmcdonalda]

Yes,

tried to use it for both, the array declaration:

UPROPERTY(BlueprintReadWrite, EditAnywhere, Instanced, Category = "Config", meta = (ShowOnlyInnerProperties))
TArray<UDebugVisualizationShape*> ShapesToDraw;

and for Object class declaration:

UCLASS(Abstract, DefaultToInstanced, EditInlineNew, ClassGroup = "DebugVisualizationShape",
	meta = (DisplayName = "Visualization Shape", ShowOnlyInnerProperties))
class DEBUGVISUALIZATION_API UDebugVisualizationShape : public UObject

and even for each sub-class of said class:

UCLASS(ClassGroup = "DebugVisualizationShape", meta = (ShowOnlyInnerProperties, DisplayName = "Arc"))
class DEBUGVISUALIZATION_API UVS_Arc : public UDebugVisualizationShape

Sadly, this still doesn’t work:

but thanks for trying to help!

UCLASS(CollapseCategories)

Thanks! collapseCategories seems promising, will check it soon.

Much thanks @spereku!

UCLASS(CollapseCategories) works like a charm. Problem solved.
