ahref in Kichensink?

[new2extjs]

I am trying to modify Kitchen sink. I want to display breadcrumb as follows:
User Interface ->Nested List ->Cars ->Europe ->Germany ->BMW
Animations-> Slide-> Slide Left

When I click on each of them, I want to display the respective page. I am trying to do this using ahref
var url='http://xyz.com/kitchensink/#demo/'+bUrl[i];
<a target="ide" href="'+url +'">'+d[i]+'</a>

where bUrl[i] is id of respective element and d[i] is the respective element. It is working for Nested List, Slide Left, but unfortunately this logic doesn't work for User Interface, Animation, Slide, Europe, BMW, etc and the console gives the error that .....app/view/User%20Interface.js?_dc=1329397433130 404 (Not Found)
and it's obvious because these classes arenot present in Kitchen sink. I don't know why.

Can anyone guide how can we access the link for the above mentioned items in the kitchen sink?

Thanks in advance!

Is there a class requiring that JS file or are you trying to create it?

[new2extjs]

Well, there are no classes for User Interface, Animation, Slide, Europe, BMW, etc in kitchen sink. I wonder why? so the link of www.xyz.com/kitchensink/#demo/id doesn't work for them. Is there a default url or some way to access them so that when I click on User Interface, it opens that page and likewise for others?
