Panelbar like in JotForm.com?

Jotform.com uses a nice panel bar, the navigation system in the left side. It looks polished and is rich in functionality. The items have a highlig开发者_运维技巧ht and have help '?' functionality which display a preview upon hovering.

I don't know if they built it themselves. I was wondering if there's a jQuery plugin or UI Framework that helps me build something very similar. I already have Telerik's controls however this one looks cooler.

They probably did it with one of the JavaScript libraries they link to on the webpage. The probably did it with this one?

Edit: I was incorrect on closer inspection is is this file that is used when the side panel is used, but I cannot find the library that it came from.

Perhaps you could just contact them and ask?
