• CSS

• Adjust the width by changing the "#listgroup" width (in red).
• Adjust the header and selected colors by changing the color values in blue.
  
  
• Contents
  
  
  • Follow this basic template:
    
     <h3 class="head">TITLE</h3>
     <ul style="display: none;">
      <li>LIST ITEM 1</li>
      <li>LIST ITEM 2</li>
      <li>LIST ITEM 3</li>
     </ul>
    
    
  • The Header content is in orange. You can replace it with text and/or include an image.
  • The list content is in blue. I've included some additional css to float anything inside a <span> to the right (in the code, not in the basic template).
