I will try to explain once again my whole problem.
I want to use List shape (using New.List) with my own content type (own content part) and a custom menu (not only Edit item). This is what I want to achive.
So, I have already created my own content part and content type, I've already created service which return me list of my content types (including my part) and I I have already display it with List shape. But here is the problem. Default list shape
has only Edit menu item. I want to add one more item in menu but I don't know how. I thought that I can override Widget.ControlWrapper.cshtml in my module and add another menu. But this way I'am overriding whole stereotype, just you said. One solution that
I remember is to make my own List shape an logic of rendering all of the parts of my content type.
But I want to know is there any better solution to reuse existing List shape and its logic with some changes (with menu item added). And this changes must exists only when I rendering list of my content type. Rendering other content types which also use
List shape must be the same as before.
