title: Selenium IDE: how to verify that only specific values are present in radComboBox via verifySelectOptions command
body: <p>We use <code>Telerik RadComboBox</code> to implmement a drop-down list in our web application. Is it possible to use the <code>Selenium</code> command <code>verifySelectOptions</code> to validate only if specific values are present in the drop-down list?</p>
  
  <p>I'm trying to use it but I get this error message:</p>
  
  <pre><code>[error] Unexpected Exception: fileName -&gt; chrome://selenium-ide/content/selenium-core/scripts/selenium-api.js, lineNumber -&gt; 1688, columnNumber -&gt; 20
  </code></pre>
  
  <p>Does anyone have succeeded in using <code>verifySelectOptions</code> command to validate a drop-down list with <code>RadComboBox</code> control?</p>
  
  <p>PS: my purpose is to validate whether the drop-down list is displayed well as a defined list, not displayed as a non-defined list.</p>
  
  <p>Thank you.</p>
