Other than the content_for approach (which may or may not be what you want), there are a few additional options.

You could use a before_filter in your controller to set a variable:

# Controller
class TestController < ApplicationController
  before_filter :set_variable

  def set_variable
    @my_variable = true
  end
end

# Layout
if @my_variable
  # Do the controller-specific stuff you want to do
end

Or, you could leave the controller alone and just check for the controller name in your layout:

# Layout
if controller.controller_name == 'test'
  # Do the controller-specific stuff you want to do
end

Just call an appropriately named partial in your layout

<%= render :partial => "#{controller_name}_menu" %>

If your controller is WidgetsController, then this will use the partial _widgets_menu.html.erb under ./app/views/layouts

method 1: set a variable in that controller

class SomeController
  before_filter :set_to_use_menu

  private

  def set_to_use_menu
    @use_menu = true
  end
end

method 2: determine the controller's name in the layout

<%- if controller_name == "your_controller_name" %>
  <%= render :partial => "the_menu" %>
<%- end %>

If I have correctly understood the question you needs to special place in layout.

Use <%= yield(:) %> in desired position in layout, for example:

    # application.html.erb
    <%= yield(:right_menu) %>

    # show.html.erb
    <% content_for :right_menu do %>
    <!-- Everything in this block will be shown at the position yield(:right_menu) in layout -->
    <% end %>
