hi;

you can set an id attribute on any section, and then retrieve the
GMenu associated with that section, at which point you can add any
further item there, e.g.:

  <section>
    <attribute name="id">view-placeholder</attribute>
    <item>
      ...
    </item>
  </section>

then use the GMenuModel API to iterate over the menu until you hit the
section with the "view-placeholder" id attribute. at that point, you
can use the GMenu API to add items at that section. gedit has some
simple code that handles their extension mechanism for menus:

https://git.gnome.org/browse/gedit/tree/gedit/gedit-app.c#n1613

and a class that handles appending/prepending/removing menus by using
a "merge-id" attribute on the GMenuItem added by an extension.

ciao,
 Emmanuele.
