Ajax-style FAQ using a CMS?

We plan to create a FAQ website. It will include two types of content:

1. Lists of questions (FAQs), and开发者_JS百科
2. HTML for each answer.

When user chooses a list and clicks a question, the answer will load in Ajax style.

A very similar approach was described here: Ajax FAQ loading using jquery?

But, before we start developing our own CMS, we would like to make sure that no existing solution is directly applicable. So, my question is: are you aware of any existing CMS for creating Ajax-style FAQs?

We are particularly interested in WordPress plugins (one is listed in my own answer below).

Two solutions I found that are likely to be applicable:

• WP DS FAQ: FAQ management tool for WordPress. Replaces specific code on a page with a pre-defined list of questions and answers. Requires WordPress version 2.7 or higher, compatible up to 3.2.1. Last ipdated in August 2011.
• Core Design FAQ plugin for Joomla. FAQ is created out of a K2 content module. Requires Joomla version 1.7. Last ipdated in August 2011.
