[Zope3-Users] Different menu items for different views for the same context

[Baiju M]

Hi all,

I am trying to create a navigation menu where menu items should
change based on views.  To do this first I created a
viewletManager like this::

  <browser:viewletManager
     name="page_navigation_menu"
     provides=".viewlet.IPageNavigationMenu"
     class=".viewlet.PageNavigationMenu"
     layer="myapp.skinning.layer.IMyappBrowserLayer"
     permission="myapp.View"
    />

And I defined viewletManager like this::

  from zope.viewlet.manager import WeightOrderedViewletManager
  from zope.interface import implements
  from zope.viewlet.interfaces import IViewletManager

  class IPageNavigationMenu(IViewletManager):
      """Page Navigation Menu Viewlet Manager."""


  class PageNavigationMenu(WeightOrderedViewletManager):

      implements(IPageNavigationMenu)


Also I have this in my page layout::

  <div id="pagenavigation"
       tal:content="structure provider:page_navigation_menu">
    Page Navigation Menu
  </div>


This is an example viewlet::

  <browser:viewlet
     name="Add User"
     viewURL="@@add_user"
     for="myapp.main.interfaces.IMyapp"
     manager="myapp.skinning.viewlet.IPageNavigationMenu"
     class="z3c.menu.simple.menu.ContextMenuItem"
     permission="myapp.View"
     layer="myapp.skinning.layer.IMyappBrowserLayer"
     weight="2"
     />

I do not want this viewlet appear when I open some views
registerd for `myapp.main.interfaces.IMyapp`.  How can I do that
? Can I use "layer" feature in some way to solve this ?
or anything I missed here ?
