title: Adding text to a combobox
body: <p>Currently I have a simple ComboBox that populates with 3 items when clicked:</p>
  
  <pre><code>        With FunctionBox
              .AddItem "Add Blank Issue"
              .AddItem "Move Existing Issue"
              .AddItem "Reorder Issues"
          End With
  </code></pre>
  
  <p>However, the combobox is empty before the dropdown arrow is selected.</p>
  
  <p>When the combobox appears I want it to show something like, "Please select one of the options below".</p>
  
  <p>I tried setting the 'Value' of the combobox to 'test'.  Test shows up in the editor, but does not when I run the application.</p>
  
  <p>I also want to make sure the string goes away when the down arrow is selected and the user cannot interact with it.</p>
  
  <p>Any advice? </p>
  
  <p>I can provide screenshots if this is somewhat unclear.</p>
  
  <p>Thanks!</p>
