title: set cell value as hyperlink in mxGraph
body: <p>I am working on the mxgraph and in the graph page when we select a cell and gives a value it should be displayed as hyperlink only. But when i used html,anchor tag or in other ways, the entire code displays in the cell as a text. Even if i try to input the value dynamically also it displays as text.</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true">
  <div class="snippet-code">
  <pre class="snippet-code-html lang-html prettyprint-override"><code>  var Element123 = "&lt;html&gt;&lt;a href=''/Graph/Graph/' + globals.getProjID() + '/' + newValue +' '&gt;' "+ selctedItem +" &lt;/a&gt;&lt;/html&gt;"
              this.graph.labelChanged(cell, Element123, evt);
              this.graph.getModel().endUpdate();
          }</code></pre>
  </div>
  </div>
  </p>
  
  <p>here the newValue is the ID of the selected option from the dropdown.</p>
