title: select multiple dates by dragging over datepicker dates
body: <p>I am using Extjs datepicker.
  I want to select multiple dates of datepicker by dragging over them. </p>
  
  <p>For that I tried to make calendar dates draggable. I took the reference from here <a href="https://docs.sencha.com/extjs/5.1/core_concepts/drag_drop.html" rel="nofollow">https://docs.sencha.com/extjs/5.1/core_concepts/drag_drop.html</a> and wrote below mentioned code.</p>
  
  <pre><code>var calendarDate = Ext.get('DatePickerSchedule').select('td');
          Ext.each(calendarDate.elements, function(el) {
              var dd = Ext.create('Ext.dd.DD', el, 'datesDDGroup', {
                  isTarget: true
              });
              //Apply the overrides object to the newly created instance of DD
              Ext.apply(dd, window.overrides);
          });
  </code></pre>
  
  <p>But it doesn't seems to be working. Please suggest what I am missing.</p>
