Blazor Layouts with several placeholders (Header/Footer/etc) like MVC Sections/WebForms

[chrdlx]

What I'm trying to achieve is a component like this:

@inherits LayoutComponentBase
<div>
   Here some html from the layout's header...
  @ExtraHeader

   Here will be the child body: 

   @Body

   Now some footer... 
   @ExtraFooter
   Some more footer...
</div>

Suppose I want to dedicate that @extraheader and @ExtraFooter to be implemented by all the children who use this layout that need to. Is this possible in Blazor right now somehow?

I know we have @Body, but that only supports nesting, not putting content in other places like MVC Sections.
You could do that too in webforms with something like this inside a MasterPage:

<asp:ContentPlaceHolder id="Header" runat="server"></asp:ContentPlaceHolder>
<asp:ContentPlaceHolder id="Body" runat="server"></asp:ContentPlaceHolder>
<asp:ContentPlaceHolder id="Footer" runat="server"></asp:ContentPlaceHolder>

Thanks!

Thanks for contacting us, @chrdlx.
This is an area we have been debating about quite a bit. We're going to think more about this in the coming future and decide how we move forward from there.
