Hi,

The linked article is a bit outdated, that is why it is no longer accessible.

Nevertheless, you could create a FAQ section using the following way:

At first, I would like to point you to the following section of Developer’s guide about document types:
http://devnet.kentico.com/docs/devguide/index.html?document_types_overview.htm

If you do not want to use pre-defined document type CMS.FAQ document type, you need to create a new document type that will represent a FAQ item.

Now that you have created a new document type, you need to prepare the transformations that will be used for displaying FAQ details: http://devnet.kentico.com/docs/devguide/index.html?document_types_transformations.htm

Then, you can create FAQ documents in the content tree as it described here:
http://devnet.kentico.com/docs/devguide/index.html?creating_a_new_structured_document.htm

and use standard Repeater web part to display them.

If you want to display something using Repeater, you need to specify at least following properties:
Path - path of the documents to be displayed
Document types - types of documents that should be displayed, separated with a semicolon
Transformation name - transformation used in the list view mode

Best regards,
Filip Ligac
