Add a Expand-Collapse Sidebar Widget

Expand Collapse System is very awesome be'coz it give a very Professional feel to blog and as MBT first launched their expand collapse widget in the comment bar, so many blog owners use that system in their blog but as using the jQuery and other languages so that doesn't work work in many blogs but this widget will work in all kind of blog be'coz this you have to add this widget  in the HTML/JavaScript Widget so you don't need to make changes in your template editor. This Widget is simply a made by the CSS for designing and using the JavaScript and some other elements to perform this particular task in this widget.

This idea came in my mind by watching the comment box of blogger which perform same task.
