What is the most effective method for organizing nested views?

I am seeking guidance on the recommended approach for nesting Backbone Views.

Here are some possible methods for nesting views:

  1. Rendering all views and assembling them in the Router
  2. Having an IndexView handle all nesting, which is then called in the router
  3. Including views in Underscore templates

I have already experimented with this concept in the following fiddle: http://jsfiddle.net/m48Nc/2/

Note: I am aware that the example does not function properly; it merely displays the current structure that I have been working on but am not satisfied with.

Which method should I pursue? Any relevant links or resources would be appreciated ;)

UPDATE:

Based on responses from fguillen and other discussions I came across, we can achieve the following:

var IndexView = Backbone.View.extend({

    tagName: "div",

    className: "container",

    template: LayoutTemplate,

    render: function() {
        this.$el.html(LayoutTemplate);

        this.$('div.content').html(ContentTemplate);
        this.$('div.sidebar').append(new LoginView().render().el);
        this.$('div.sidebar').append(new RegistrationView().render().el);

        return this;
    }

});

Utilizing templates for dynamically appending complex elements within each other is not recommended. Templates are designed for simpler Model.attributes.

Instead of using a template for your MenuView, it is suggested to define the Menu frame as a regular element in the HTML DOM and then instantiate the MenuView by assigning this DOM element to the View.el like so:

var menuView = new MenuView({ el: "#menu" });

To render subViews within the MenuView, jQuery's append, html, and other manipulation functionalities can be used:

// code simplified and not tested
var MenuView = Backbone.View.extend({
  render: function(){
    // the this.$el is already rendered

    // list of elements
    this.collection.each( function( model ){
      var modelView = new ModelView({ model: model });
      this.$el.append( modelView.render().el );
    }, this);

    // additional subViews
    var loginView = new LoginView();
    this.$el.find( "div#login" ).html( loginView.render().el );

    // another way to add subViews
    var loginView = new LoginView({ el: this.$el.find( "div#login" ) });
    loginView.render();
  }
});
