title: What is default value for "optionLabel" of the HTML DropDownList?
body: <p>So if Set up a DropDownList where Text: <code>"people names" (string)</code>and Value:<code>studentID (int)</code>. in my view like this (assuming myDDL is data from code-behind placed in the viewbag)</p>
  
  <pre><code>     @Html.DropDownList("myDDL", (IEnumerable&lt;SelectListItem&gt;)ViewBag.myDDL,  
       "Select Stuff", new Dictionary&lt;string,object&gt;{
        {"class","dropdowns"},{"id","myDDL"}})  
  </code></pre>
  
  <p>What is the value of "Select Stuff" which is an optional label that appears at the beginning of the dropdown list?</p>
  
  <p>I'd like the value because it if no value is selected then I'd like to get all the data. </p>
  
  <p>Thanks!</p>
