title: How can I use relativeTo property in html template along with routerActive?
body: <p>I need to use 'relativeTo' property as well as 'routerLinkActive' directive in my application.
  Having a click listener function that routes using </p>
  
  <pre><code>router.navigate(this.router.navigate(['path']{relativeTo:this.route});
  </code></pre>
  
  <p>would be okay. But in that case I cannot use the routerLinkActive directive.</p>
  
  <p>How can I simultaneously use both?</p>
