Synergy has published on its official blog some sample code on how to built a SharePoint JQuery WebPart. This accordion WebPart it’s visually appealing and offers a decent option for having some dynamic UI interaction.
I decided to create a Visual Studio 2010 solution project for easelly deploy and use of this code. The following link you can find zip file.
Also recorded a Youtube video on how to install and use this WebPart. It’s in spanish language!
Hope it helps!
