show/hide with same ids
<p>I searched a lot on Stackoverflow, solution for my question, but no one of them helped me. I have a multiple show/hide (toggle) content, with same id's and I want to make, that the only one of them, what I need, opens, not all of them. There's my <a href="https://jsfiddle.net/p6a7k3cw/2/" rel="nofollow noreferrer"><strong>JSFiddle</strong></a> You can test it.</p>

<p>This is my JavaScript</p>

<pre><code>$("#view").click(function(){
  $('.hidden-content').slideToggle(500).toggleClass("active");
});
</code></pre>
