title: Change row count doesn't work in materialize css text area
body: <p>In <a href="http://materializecss.com/forms.html" rel="noreferrer">materialize css text area</a>, is it possible to initialize the text area with a specific row count using "rows='20'" ? How can we increase the default row count ?</p>
  
  <p>code which doesn't work:</p>
  
  <pre><code>&lt;div class="input-field col s12"&gt;
     &lt;textarea id="textarea1" class="materialize-textarea" rows="20" &gt;&lt;/textarea&gt;
     &lt;label for="textarea1"&gt;Text&lt;/label&gt;
  &lt;/div&gt;
  </code></pre>
