title: vuejs model for checkbox group
body: <p>I have 2 arrays one for possible checkbox variants and one for already saved-checked boxes.VUEJS template for example</p>
  
  <pre><code>&lt;ul&gt;
                  &lt;li v-for="cit in possable"&gt;
                      &lt;label&gt;
                      &lt;input  
                          type="checkbox"
                          :checked="savedcbx.indexOf(+cit.id)&gt;-1"
                          :value="cit.id"/&gt;
                      {{cit.rname}}
                      &lt;/label&gt;
