I only spent about 30 minutes coding this. But I needed it because some accordion's I use in my app got too crowded.
This panel lets you "rollup" a panel in the accordion, and roll it back down again, so you can use all the vertical space when needed.
View the demo and let me know what you think. The code needs improvement and I tried to make a toggle tool icon that changed when clicked, but couldn't figure it out.
