title: AngularJS change multiple partials per request
body: <p>I am new in node.js and Angular and I am creating a web application.</p>
  
  <p>At the moment I have the following design of my application - the screen is separeted by three columns - the left one is my menu and both middle and right columns are used to display the content. Sometimes when I click some of the elements in the menu I want to change only the middle column, if I click another menu element I want to change the partial in the right column and in other cases I want to change both middle and right columns per click in the menu.</p>
  
  <p>I can't use ng:view because it doesn't allow me to use multiple ng:view elements. So I am wondering what is the best decision here. At the moment I am using ng:hide but it is not a good desicion. In the end I will have maybe 20 variables in my application which values I should update after every request.</p>
  
  <p>Thanks!</p>
