    <p>The fiddle you've mentioned works well in my local project on my machine. For some reason, it doesn't work on fiddle site. Try running it on your local project.</p> <p>Still instead of using <code>onBackButtonTap</code> config, it's good to extend <code>Ext.navigation.View</code> class and override <code>onBackButtonTap</code> method. That way you'll have more control over whole components. You'd also like to override other configs as well. Here's what I'd use - </p> <pre><code>Ext.namespace('Ext.ux.so'); Ext.define('Ext.ux.so.CustomNav',{ extend:'Ext.navigation.View', xtype:'customnav', config:{ }, onBackButtonTap:function(){ this.callParent(arguments); alert('back button pressed'); } }); </code></pre> <p>the line <code>this.callParent(arguments)</code> will allow component to behave in default way + the way to wanted it to behave. And if you want to completely override the back button behavior you can remove this line. Try doing both ways.</p> <p>To use this custom component, you can use - </p> <pre><code>launch: function() { // Destroy the #appLoadingIndicator element Ext.fly('appLoadingIndicator').destroy(); var view = Ext.create('Ext.ux.so.CustomNav', { fullscreen: true, items: [{ title: 'First', items: [{ xtype: 'button', text: 'Push a new view!', handler: function() { //use the push() method to push another view. It works much like //add() or setActiveItem(). it accepts a view instance, or you can give it //a view config. view.push({ title: 'Second', html: 'Second view!' }); } }] }] }); } </code></pre> <p>Give this a shot. It'll work for you yoo.</p>

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.
