title: Dropdown field - first item should be blank
body: <p>Using sharepoint build in lookup column and it set to required field. SharePoint automatically selects the first item in the dropdown box (kinda misleading for the end users).</p>
  
  <p>Is there a way to display blank or Null for the first row of this drop down box?</p>
  
  <p>(I am open to any solution. I prefer javascript type solution)</p>
