body: <p>I am working on the Cascading Dropdowns for the Sharepoint.</p>
  
  <p>I am able to implement this without any issue.</p>
  
  <p>Now my problem is How to filter the First dropwdown Fill value using caml query.</p>
  
  <p>E.g. I have list of projects and tasknames according to the Projects.</p>
