This demonstrates how you create a visual query, which can be configure by the admin

So if you go edit in this module and change the sort-property, it will affect the sort in the Visual Query

Current Configuration

  1. Default Sort-Order if NOT specified in the Url: [Content:SortOrder] [Content:Toolbar]
  2. Demo: use URL sorting instead: A-Z or Z-A or reset

Result

  1. [Fdbk:Subject]
