title: Change URL in address bar without having to reload
body: <p>I've found a lot of questions about changing the url (without reloading).
  Some answers were - use plugins, use <code>location.hash</code> ..., or with reloading</p>
  
  <p>But none of them worked for me.</p>
  
  <p>On website I have a dropdown menu, and on its change the url parameter should have changed.</p>
  
  <p>So what I'm trying to do is:</p>
  
  <p>I want to change: <code>www.foo.com?country=Germany</code> into  <code>www.foo.com?country=Slovenia</code> without reload.</p>
  
  <p>Is what I am trying to achieve even possible?</p>
