This plugin allows you to get better control on how your categories are listed. It provides a widget which lets you get more options than the default WordPress category widget (show RSS, hide empty categories, etc.). Furthermore, it allows to hide the children categories and use clickable buttons to expand them. The plugin requires jQuery to be included in your theme. It degrades nicely when javascript is not available to the usual WordPress category list.
