title: "Add new item" button within asp.net mvc dropdown list
body: <p>Currently, I am adding items to a dropdown list in my asp.net mvc application by clicking on a link on the same page and adding an item to the database table that the dropdown list is bound to. </p>
  
  <p>I want this "link" to be an item WITHIN the drop down list so the list items will look something like</p>
  
  <ul>
  <li>Item 1</li>
  <li>Item 2</li>
  <li>Item 3</li>
  <li>Add New Item</li>
  </ul>
  
  <p>and when the user selects "add new item", a dialog will pop up where the user can enter something to add to the list. </p>
  
  <p>I've been searching all over the internet for a solution to this and I cannot find anything, can anyone point me in the right direction?</p>
  
  <p>Thanks!</p>
