List Manager

I am wondering if someone knows of a plugin which will help automate the management of a list of things on a page. We have a list of items which we constantly update and change, and doing so by hand is a pain. Would love to have a css/ajax type list management tool which we can use to easily sort, reorder and update lists on a page. Searched like crazy but words like “list” and “sort” etc yield a wide variety of results which are not what I’m looking for. Any help would be appreciated. Thanks so much!
