Selenium to click on the title from a drop down menu

Question

I am in middle of a selenium application development using C#. I have a drop down menu on a webpage. I want selenium to click on the exact name after clicking the drop down menu. I am successful on clicking drop down menu now and I can view the titles or options on that menu.

What I want is that I need selenium to click on the title based on what the user gave when the application is first opened. Actually the menu button is not visible, but when I make mouse hover the name, it is visible.

I have tried

var menu = driver.FindElement(By.ClassName("ms-vb"));
SelectElement sel = new SelectElement(menu); 
sel.SelectByText(text);

where text is the user entered text. While running the app it throws an error like

"Element should have been select but was img"

How can I solve this??My task is onhold due to this..

Any comments will be really appreciated..

Thanks

I hope this is the code that you require:

<table cellspacing="1" cellpadding="0" height="100%" onmouseover="OnMouseOverFilter(this)" class="ms-unselectedtitle"
sortfields="SortField=Unify%5fx0020%5fApp&amp;SortDir=Asc&amp;View=%7b696D6B29%2d5A5D%2d47F3%2d97CF%2dECBFDD1E2CE8%7d"
resulttype="" fieldtype="Lookup" displayname="Unify App" ctxnum="1" name="Unify_x0020_App" filterable="" filterdisable=""
sortdisable="" sortable="" style="width:100%;" id="msomenuid2">
  <tbody>
    <tr>
      <td width="100%" nowrap="nowrap" class="ms-vb">
        <a sortingfields="SortField=Unify%5fx0020%5fApp&amp;SortDir=Asc&amp;View=%7b696D6B29%2d5A5D%2d47F3%2d97CF%2dECBFDD1E2CE8%7d"
        onclick="javascript:return OnClickFilter(this,event);" href="javascript:" title="Sort by Unify App"
        onfocus="OnFocusFilter(this)" id="diidSortUnify_x0020_App">Unify App
        <img width="1" border="0" height="1" alt="Use SHIFT+ENTER to open the menu (new window)." class="ms-hidden"
        src="/_layouts/images/blank.gif" /></a>
        <img border="0" alt="" src="/_layouts/images/blank.gif" />
        <img border="0" alt="" src="/_layouts/images/blank.gif" />
      </td>
      <td style="position: absolute; right: 1px;" class="">
        <img width="13px" alt="Open Menu" style="visibility: hidden;" src="/_layouts/images/menudark.gif" />
      </td>
    </tr>
  </tbody>
</table>

If it is not a normal element the SelectElement class will not work.

This is how I deal with javascript dropdowns:

    //Click on the dropdown
    driver.FindElement(By.ClassName("ms-vb")).Click();
    //Wait for the result list to appear
    wait.Until(x => x.FindElement(By.LinkText("Target link to click")));
    //Click on the result you want
    driver.FindElement(By.LinkText("Target link to click")).Click();

If the result is not a link you should use xPath to locate it by its text. Ex.

    driver.FindElement(By.XPath("//*[text()='Target text']")).Click();

Hope it helps.
