# FullyExpand - **使用位置:** UPROPERTY - **元数据类型:** bool - **关联项:** [ShowInnerProperties](ShowInnerProperties/ShowInnerProperties.md) 但是没有发现该Meta被使用的原理代码。 在源码中搜索发现有多处应用,但实际上没有原理代码。 ```cpp /** The options that are available on the node. */ UPROPERTY(EditAnywhere, Instanced, Category = "Options", meta=(ShowInnerProperties, FullyExpand="true")) TObjectPtr SelectOptions; /** The currently selected option. */ UPROPERTY(EditAnywhere, Instanced, Category = "Options", meta=(ShowInnerProperties, FullyExpand="true")) TObjectPtr SelectedOption; ```
