title: iPhone/iPad UI: seeking drop-down control
body: <p>My universal app has a settings page, wherein the user must choose a theme from a dozen available themes.</p>
  
  <p>Problem is, if I am using a picker-view, it takes up most of the screen on an iPhone.</p>
  
  <p>I think what I want is something like your standard Windows drop-down menu, where it just displays on a single line the current selection, and clicking it expands into a scrollable list of possible items.  Selecting an item collapses the list back into the original form.</p>
  
  <p>So my question is:  What is my best method for handling this situation?  Can anyone point me to pictures or code examples of how this situation is handled successfully?</p>
  
  <p>EDIT:
  This is the behaviour I'm looking for:</p>
  
  <ul>
  <li>only the currently selected profile is displayed</li>
  <li>when the user taps on this, it expands into a list</li>
  <li>when the user selects an item (or taps outside of the view) it collapses back to its original form, now displaying the new selection</li>
  </ul>
  
  <p>ie functionally equivalent to a dropdown.</p>
