title: How to modify v-for or use v-for with different step?
body: <p>Let's say that I have an array </p>
  
  <blockquote>
    <p>arr = [1,2,3,4,5,6,7,8,9]</p>
  </blockquote>
  
  <p>How can I use v-for to get the following result:</p>
  
  <pre><code>&lt;template&gt;
      &lt;div&gt;
          &lt;div v-for="elem in arr"&gt;
              // here i need to produce a div every 4 steps
              // each div will contain 4 elements in right order
          &lt;/div&gt;
      &lt;/div&gt;
  &lt;/template&gt;
  &lt;script&gt;
  export default {
      name:home,
      data(){
          return {
              arr:[1,2,3,4,5,6,7,8,9],
          }
      }
  }
  &lt;/script&gt;
  
  </code></pre>
  
  <p>So I get 3 div and each one contains 4 elements.</p>
