title: how to create dynamic filter in text area of spotfire
body: <p>I want to create a dropdown in text area to filter data in table dynamically.</p>
  
  <p>I have many entries under Filter "Task Description".</p>
  
  <p>But I want to create a dropdown in text area with only below three entries out of all entries.</p>
  
  <ul>
  <li>All - it will show the entire data</li>
  <li>Prasanta - this selection will only show Prasanta related rows</li>
  <li>Chandan - this selection should only show Chandan related rows.</li>
  </ul>
  
  <p>Is it possible?</p>
