Why do the widget elements not show in hierarchy?

After i create these elements (UcanvasPanel, UVerticalBox, UProgressBar and UTextBlock) in my [MyUserWidgetBase.h][1] and [.cpp][2] files,

the elements dont show up in the [hierarchy table][5] even though i have the MyUserWidgetBase as the Parent class, but they do show up in the [details panel][6]. How can i make them show up in the hierarchy or how can i use these elements in the UI.

Widget Blueprint editor wont show dymanicly created widgets as creation code does not inform widget editor that widgets been placed. You need to use BindWidget meta specifier in UPROPERTY (meta=BindWidget), and you don’t need to initiate the widget, UUserWidget class should handle that
