title: Condition to check select2 dropdown for mandatory field validation
body: <p>I have multiple select2 dropdowns and text fields,I need to do validation for text fields and dropdowns. I am able to validate the text fields but not the dropdown fields.</p>
  
  <p>I have written a class for dropdown and text fields as MandatoryDD and MandatoryTxt. </p>
  
  <p>I am able to validate all the text fields but unable to iterate through dropdown fields, is there any way to check the dropdown value(check the first dropdown value which is 'SELECT' option in my case or check the index number(0 in my case)</p>
