jQuery hover selector filter
<p>I have tried to find out this on jQuery documentation but I haven't sort it out.</p>

<p>What I am trying to achieve is that when I am hover ".box" the ".inside-box" appears but I only want the one inside the box I am hover and not all of them. </p>

<p>This is a simplified version of the code.</p>

<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>    jQuery(document).ready(function($) {
        $(".box").hover(
         $("this").filter($(".inside-box")).toggle();
        );
    });</code></pre>
<pre class="snippet-code-css lang-css prettyprint-override"><code>.box {
  display:inline-block;
  width:30%;
  margin-left:20px;
  background-color:gray;
  color:white;
 }

.inside-box {
  display:none;
 }</code></pre>
<pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"&gt;&lt;/script&gt;

&lt;div class="box"&gt;
   &lt;div class="inside-box"&gt;hi&lt;/div&gt;
&lt;/div&gt;

&lt;div class="box"&gt;
   &lt;div class="inside-box"&gt;hi&lt;/div&gt;
&lt;/div&gt;

&lt;div class="box"&gt;
   &lt;div class="inside-box"&gt;hi&lt;/div&gt;
&lt;/div&gt;</code></pre>
</div>
</div>
</p>
