angularjs - ng-route : How to render layouts by path?

I'm sorry not good at English well, please understand the subject is not good.

I am creating a SPA with angular.js.

I want to change or append view by path using ng-route.

For example,

 menu1

 menu2

  

  

When the select top menu, then leftMenu shuld be changed.
And I access the link which is #/menu1/someContent then leftMenu and content should be changed.

What I have to do implementing these process?
