Also the url should be set to "/item/21"
$route is that it causes a complete refresh.ng-click and setting the item, is that the url wont change and hence cant be bookmarked. The angularjs site implements something similar for their api and tutorial search sections.
What are my options for implementing the above ?
By "complete refresh" I'll assume that means the entire page is getting refreshed. One way to work around this is to put the left pane contents directly into your index.html page, and only use ng-view to control the right pane:
<div ng-controller="...">
<!-- left pane stuff here -->
</div>
<ng-view><!-- right pane stuff will show up here --></ng-view>
