    <p>The majority of Backbone tutorials that deal with master-detail scenarios handle the detail state by creating new views with models passed from routes (<a href="http://coenraets.org/blog/2011/12/backbone-js-wine-cellar-tutorial-part-1-getting-started/" rel="nofollow">example</a>). I'm wondering what the alternative options are what the pros and cons are for each.</p> <p>The thing that has always stood out to me about this approach of instantiating new views is that it seems like a missed opportunity to make use of Backbone's model-view binding. I.e., create a single detail view that updates based on the selected model. But this would require a separate model concerned only with the UI / active state.</p> <p>I can think of three different patterns:</p> <ul> <li>Create/Destroy views for each active detail. (This seems like excess work, not to mention potential <a href="http://lostechies.com/derickbailey/2011/09/15/zombies-run-managing-page-transitions-in-backbone-apps/" rel="nofollow">zombie problems</a>)</li> <li>Maintain an additional model that represents the active detail and create one view that re-renders itself when the model updates</li> <li>Create one view with a method that swaps out the associated model (I think this can lead to event binding problems and is probably not a good idea)</li> </ul> <p>In the context of a simple case like the example tutorial linked above, what are the pros/cons? Is the idea in #2 of using a UI model a bad practice? Are there other solutions? </p>

    1. COi created a treeview using Flat backbone.js models. It is pretty much easy, may be you can talk about your scenario so that i can provide direct solution :) btw the problem depends on what you take as the model and view rest is just programming ( you would use recursion inside render method to build the visual view )

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.
