title: how to assign values to paper-items in a paper-dropdown-menu in polymer when using an array?
body: <p>I want to assign values to the paper-items like below </p>
  
  <pre><code>&lt;paper-item value="1"&gt;label1&lt;/paper-item&gt;
   &lt;paper-item value="2"&gt;label2&lt;/paper-item&gt;
   &lt;paper-item value="3"&gt;label3&lt;/paper-item&gt;
  </code></pre>
  
  <p>but I am using an array to get my labels dynamically this way</p>
  
  <pre><code> &lt;paper-dropdown class="dropdown" on-core-overlay-open="{{comboDrop}}"&gt;
          &lt;core-menu class="menu"&gt;
           &lt;template repeat="{{processlist}}"&gt;
                &lt;paper-item&gt;{{}}&lt;/paper-item&gt;
              &lt;/template&gt;
          &lt;/core-menu&gt;
      &lt;/paper-dropdown&gt;
  </code></pre>
  
  <p>I assign an array to processlist later on when I get the required information.
  like </p>
  
  <blockquote>
    <p>processlist=arr</p>
  </blockquote>
  
  <p>, which allows me to display those labels in the paper-dropdown-menu.</p>
  
  <p>How can i assign values to the paper-items and how can I access the values corresponding to each label ? I know that </p>
  
  <blockquote>
    <p>detail.item.textContent</p>
  </blockquote>
  
  <p>gets you the label, how can we get the values similarly</p>
  
  <p>I'm fairly new to javascript and polymer components so any help in the right direction would be appreciated. </p>
  
  <p>Thanks !</p>
