    <p>From what you're saying, it sounds like you really only want a single collection instance, which will hold the items that you're referring to (model instances in the collection).</p> <p>There should also be 3 views in this scenario — one for the <code>List</code> (the left panel), one for the individual <code>ListItem</code>s in that list and one for displaying information about the <code>Item</code> itself (the right panel).</p> <h2>List</h2> <p>The <code>List</code> view holds a reference to the collection and appends a <code>ListItem</code> view for each item in the collection. You may later want to subscribe to events on the collection to automatically append/remove items from the list when new ones are added/remove from the collection. This is the view where that should be handled.</p> <pre><code>List = Backbone.View.extend({ el: '#list', initialize: function(){ _.bindAll(this) this.collection.each(this.appendItem) }, appendItem: function(item) { view = new ListItem({model: item}) $(this.el).append(view.render().el) } }) </code></pre> <h2>ListItem</h2> <p>The <code>ListItem</code> view holds a reference to a particular model and renders the list item inside the list for that model. It also handles the click event, which renders the <code>Item</code> view for that model.</p> <pre><code>ListItem = Backbone.View.extend({ tagName: 'li', events: { "click" : "showInfo" }, initialize: function(){ _.bindAll(this) }, render: function(){ $(this.el).html(renderTemplate("listItem", this.model)) return this }, showInfo: function(){ view = new Item({model: this.model}) $('#item').html(view.render().el) } }) </code></pre> <h2>Item</h2> <p>The <code>Item</code> view also holds reference to a particular model and renders information about that model. This is the right panel that you're referring to.</p> <pre><code>Item = Backbone.View.extend({ initialize: function(){ _.bindAll(this) }, render: function(){ $(this.el).html(renderTemplate("item", this.model)) return this } }) </code></pre> <p><a href="http://jsfiddle.net/XRGFe/" rel="nofollow">Here is a fiddle</a> to show things in action.</p>

    1. COThank you for your answer, it gave me some idea to proceed. But, the app is a little more complex. The right view is a combination of 3 subviews and one of the sub-views is a newsfeed, which has commenting features. So, how do I manage the Model/Collection of newsfeed with that of the left view? Each leftListItem when clicked should show corresponding newsfeed and 2 other subviews

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.
