SqueezeBox

There is a very cool sliding accordion on Apple's Store site to compare various computers (click compare then scroll).

SqueezeBox is a jQuery plugin written to emulate that effect. It was designed to use the same themes available for jQuery UI, or you can add your own theme.

Click on the image or go to the demo page.

Features:

• Easily change the theme but just loading in a different jQuery UI theme (Redmond theme shown).
• SqueezeBox works with both collapsible and non-collapsible blocks.
• Activate a header numerous ways:
  
  
  1. Use browser hash marks to target the header ID - used on initial page load.
  2. Click on any header to make it active - all headers above it will collapse using a smooth animation.
  3. Use the script to set the active header.
