title: Hide reorder button in a multifield
body: <p>I have a dialog with a multifield with custom xtype. As per the requirement, I don't require the re-ordering functionality of the multifield elements. Is there a way to hide these buttons.</p>
  
  <p>Dialog xml is as follows.</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;
  &lt;jcr:root xmlns:cq="http://www.day.com/jcr/cq/1.0" xmlns:jcr="http://www.jcp.org/jcr/1.0" xmlns:nt="http://www.jcp.org/jcr/nt/1.0"
      jcr:primaryType="cq:Dialog"
      height="{Long}800"
      width="{Long}1200"
      xtype="dialog"&gt;
      &lt;items
          jcr:primaryType="cq:Widget"
          xtype="tabpanel"&gt;
          &lt;items jcr:primaryType="cq:WidgetCollection"&gt;
              &lt;tabs
                  jcr:primaryType="cq:Panel"
                  title="Questions &amp;amp; Answers"&gt;
                  &lt;items jcr:primaryType="cq:WidgetCollection"&gt;
                      &lt;tabs
                          jcr:primaryType="cq:Widget"
                          addItemLabel="Add a question"
                          fieldDescription="Note: &amp;#xa;1. Add the questions first in a row.&amp;#xa;2. Please select answer type before start adding the answers."
                          name="./questionStack"
                          xtype="multifield"&gt;
                          &lt;fieldConfig
                              jcr:primaryType="nt:unstructured"
                              xtype="apps.nirmal.widgets.configurableQandAfield"/&gt;
                      &lt;/tabs&gt;
                  &lt;/items&gt;
              &lt;/tabs&gt;
          &lt;/items&gt;
      &lt;/items&gt;
  &lt;/jcr:root&gt;
