title: Angular 5 remove specific DOM elements
body: <p>I have a small issue that I can't figure out how to do. I am just learning Angular / Typescript and I can't figure out how I could remove some DOM elements.
  I have some auto generated content, that has specific CSS classes. Unfortunately The objects are generated somewhere else and I cannot configure them in any way so I cannot add any ngIf or anything else on that content, that would simplify my work... I just have to use them. 
  What I want to achieve is something like this( jQuery version): </p>
  
  <pre><code>$("#button").click(function() {
      $('.fc-oss').toggle();
   });
  </code></pre>
  
  <p>I have a toggle and I want to attach an event to it that when it's being activated, it hides/ shows all elements with that specific type from the view. I am trying to achieve this in angular without jQuery but with little success. Any ideas on how I might be able to achieve this ?</p>
