body: <p>Please take a look at this image.
  <img src="https://i.stack.imgur.com/aPcq3.png" alt="Search"></p>
  
  <p>In the drop down list is a collection of search options. What I want is to trim these options down to only equal and not equal. I do not want the other options showing. I have tried to do
  but it does not work. Any help appreciated.</p>
  
  <pre><code>navGrid("#pager", {search:true, edit:false,add:false,del:false,searchtext:"Search",refreshtext:"Refresh" },
                    {sopt: ['eq','ne']}      
         );
  </code></pre>
