title: How to get the links to the front when reparenting
body: <p>All the cells/elements are embedded on top of other cell but the links are hidden behind the element. How do I get the links on top of the element(parent)</p>
  
  <p>Here's the <a href="http://postimg.org/image/tn3ql559z" rel="nofollow">Preview</a></p>
  
  <p>I tried with <code>link.toFront()</code> which isn't working. Below is my code snippet:</p>
  
  <pre><code>paper.on('cell:pointerdown', function (cellView, evt, x, y) {
  
                      var cell = cellView.model;
                      if (!cell.get('embeds') || cell.get('embeds').length === 0) {
                          // Show the dragged element above all the other cells (except when the
                          // element is a parent).
                          cell.toFront();
                          link.toFront();
  
                      }
  
                      if (cell.get('parent')) {
                          graph.getCell(cell.get('parent')).unembed(cell);
                      }
                  });
  </code></pre>
