body: <p>everyone, I encounter a problem when I try to filter the drop down list.</p>
  
  <p>The situation is I wish to filter the Agent dropdown list by using the Company dropdown list in same view/form. Since I need to display the Agents that only belong to the selected Company. But I have no idea to do that.</p>
