title: On click outside of some element in vue without packages
body: <p>I am wondering how can we hide all shown elements on click outside from those elements in vue:</p>
  
  <pre><code>&lt;button @click="div1=true"&gt;Show div 1&lt;/button&gt;
  &lt;div v-if="div1"&gt;DIV 1&lt;/div&gt;
  
  &lt;button @click="div2=true"&gt;Show div 2&lt;/button&gt;
  &lt;div v-if="div2"&gt;DIV 2&lt;/div&gt;
  </code></pre>
  
  <p>How can I hide all divs besides div 1 if I click on div 1 or hide all divs on click on some random part of the page?
  How does vuetify handle it?</p>
