title: Expandable TextField UI component on Blackberry/RIM OS?
body: <p>I'm planning to port an app from Android to Blackberry (targeting BB 6.0 only). On Android, I've developed a custom expandable text field component, where the user can click on a more/less link to expand the text. </p>
  
  <p>My question is whether there's an existing UI component coming with BB SDK (6.0) or any open source project that already implemented the demanded feature, or whether it also needs to be implemented from scratch.</p>
  
  <p>Some details:</p>
  
  <ul>
  <li>The expansion is animated and the
  content which is below the text field
  moves down accordingly. </li>
  <li>The text is
  non-formatted (plain text) and the
  field non-editable. </li>
  <li>The developer
  gives the max. number of lines for
  the collapsed state </li>
  <li>If the text is
  longer than it fits into the
  collapsed state, "..." is added at
  the end.</li>
  </ul>
