vscode - inherited Form

how can i create a form with inheritance in vscode ?

version 1.8.44896

inherited Form2: TForm2
TabOrder = 0
Top = 0
Width = 640

That functionality is not yet available, but it will be soon. At this moment we are working on Frame support, which is the basis for visual form inheritance, and will be released in a few weeks. Visual Form Inheritance will be implemented after that.
