    <p>Ok lets simplify what you are trying to achieve:</p> <ul> <li>Go to 'News' route, add additional menu</li> <li>Move away from 'News' route, remove the news sub-menu</li> </ul> <p>Now in vanilla Backbone, the only way to do is to do it manually. Something like this:</p> <pre><code>var Router = Backbone.Router.extend({ onBeforeRoute: function () { if (this.subMenuView) this.subMenuView.$el.empty(); // anything else you need to do }, ... //Default route. index: function () { this.onBeforeRoute(); var self = this; }, about: function() { this.onBeforeRoute(); this.aboutView = new AboutView({el:'#topContent'}).render(); }, news: function() { this.onBeforeRoute(); this.newsView = new NewsView({el:'#topContent'}).render(); this.subMenuView = new SubMenuView({el:'#subMenu', collection:this.subMenuCollection}).render(); }, ... } </code></pre> <p>Check out <a href="http://backbonejs.org/#View-remove" rel="nofollow">the docs here</a> to see about the remove method.</p> <p>One other thing I would suggest, is instantiating your views in your initialize method. If you keep recreating them every time a route is fired, the old views hang around in memory and are still bound to the DOM, causing strange issues if your views are bound to data etc. I can see you have something happening to stop this in the <code>close</code> method you have implemented, but it looks like you're not actually calling it anywhere.</p> <p>Also, I would say it is frustrating when you first try to get to grips with Backbone, but stick with it, and keep reading articles on best practices etc, cause you always need to remember that Backbone IS NOT A FRAMEWORK! It is a very simple library, it offers nothing really in the way of conventions or ways to structure your application (which is why many people like it). I love Backbone but I actually use it along with <a href="http://marionettejs.com" rel="nofollow">Marionette</a>, which provides a lot of nice ways to structure your application. I recommend checking it out.</p>

    2. COAlso I just read your comments on the other answer that mention your close method. Just to clarify, that close method is only concerned with making sure that any DOM events linking the view to the DOM are removed, to stop the 'Zombie View' behaviour I mentioned in my answer.

    3. COBut this will completely remove the views, so if I click on "about" the submenu and content is gone like it should but when I click on "news" again, the submenu and its content is not available anymore at all...

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
