Nested containers are not supported

[anonymous_user_33b42a1c]

I know this is an older post, but for those coming here from a web search – It is possible to extend container classes and nest them within other containers. For example:

#include "Project.h"

class PROJECT_API TPKeyStringMap : public TMap<FKey, FString>
{
  // This class is a map of FKey to FString.
};

// ...

TMap<SomeOtherType, TPKeyStringMap> MyNestedMap;

Happy nesting!
