A very simple jQuery plugin to add vertical scrollbars to block-level elements.

Requires jQuery and the Mousewheel plugin.

Add the script to your HTML:

<script src="/js/vendor/jquery-scrollbox.js"></script>

Put a class on the container you want to make scrollable. It must have a definite height. Then select it with jQuery and call scrollbox() on it.

$('.scrollable').scrollbox();

Finally, include the styles from jquery-scrollable.css in your stylesheet (and modify to taste).
