title: jQGrid - Filter like excel spreadsheet
body: <p>I am using jQGrid 3.8. I am using datatype:"local". I have not used any server side interaction so far. My grid has inline editing option. I can add new row, add cloned row, delete row(s),pagination, sorting. </p>
  
  <p>I would like to add filter option as well. Currently I have filtertoolbar option. 
  As you could see from the script below, for three columns (Details of purchaser, Property Type and Sale Ind) filter search "equal" option has been enabled in the form of drop down.</p>
  
  <p>Problem:I would like to get drop down mode of filer for text boxes too. But since I have dynamic row addition and deletion, I couldn't find out a way to dynamically manage the drop down like filter.</p>
  
  <p>Here's what I have so far:</p>
  
  <pre><code>&lt;script type="text/javascript"&gt;

  var pptyTypeStr = ":All;0:Apartment;1:Bungalow Or Detached;2:Condominium;3:DBSS;4:Executive Condominium;5:Semi-Detached;6:Terrace";
  var saleIndVal = ["Sold", "Aborted", "Launched","All","To Be Launched"];
  var saleIndStr = ":All;0:Launched;1:Sold;2:Aborted;3:To Be Launched";
