title: v-select deactivate some items/options
body: <p>I am using vuetify's  to display dropdowns.
  The options come from my components data.
  What I would like to do now is to deactivate only some of the items in the v-select. What items are deactivated and which are activated will later on depend on the user input.
  I can only find the option to deactivate the whole v-select like by adding <code>disabled=&quot;true&quot;</code> to the v-select.</p>
  <p>My code looks like this right now:</p>
  <pre><code>                          &lt;v-row
                              v-for=&quot;(part, index) in xy&quot;
                              :key=&quot;index&quot;&gt;
                                  &lt;v-col md=&quot;3&quot; sm=&quot;3&quot;&gt;
                                      &lt;v-card ripple &gt;
                                      &lt;v-img
                                          src=&quot;src/assets/test.PNG&quot;
                                      &gt;&lt;/v-img&gt;
                                      &lt;/v-card&gt;
                                  &lt;/v-col&gt;
                                  &lt;v-col md=&quot;8&quot; sm=&quot;3&quot;&gt;
                                      &lt;v-select
                                      v- model=&quot;dropdownValues[index]&quot;
                                      :items=&quot;part&quot;
                                      hide-details
                                      label=&quot;Select value&quot;
                                      single-line
                                      @change=&quot;changeInput(index, dropdownValues[index])&quot;
                                      @click:append-outer=&quot;resetInput(index)&quot;
                                      &gt;
                                          &lt;template slot=&quot;append-outer&quot;&gt;
                                              &lt;v-icon @click=&quot;resetInput(index)&quot;&gt;
                                                  mdi-close
                                              &lt;/v-icon&gt;
                                          &lt;/template&gt;
                                          &lt;template
                                          slot=&quot;{item, index}&quot;&gt;
                                              {{ index }}
                                          &lt;/template&gt;
                                      &lt;/v-select&gt;
                                  &lt;/v-col&gt;
                              &lt;/v-row&gt;
  </code></pre>
  <p>I thought that I could do the items via this slot possibility but now I am unsure where and how to add the functionality of changing which items are deactive and which not.</p>
  <p>Thanks in advance!</p>
