title: vue.js double v-for in list
body: <p>So I'm using vue.js in my project and I've got a question: how could I display elements of v-for inside of another v-for as list items or select options?
  I have abstractly something like:</p>
  
  <pre><code>&lt;div v-for='item in items'&gt;
    &lt;div v-for='element in item.elements'&gt;
      ...
    &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>Would highly appreciate any possible help, thanks!</p>
