Sequence Display


This simple RCO is typically used as a sub-component of more complex RCOs, to gradually reveal a sequence of steps or a procedure, forcing user interaction by requiring button clicks to advance the sequence. The idea is to simplify a complex process by revealing the process gradually. It probably could be employed as a standalone RCO as well, but at present there has yet to be a need.

The instructor need only provide an XML file with a set of steps. A step consists of a label and associated text. The instructor also provides a direction for the Sequence - which specifies whether it will read vertically from top to bottom, or horizontally from left to right.

The sample XML file provided below can be populated with real data and must placed in the same location as the HTML file used to access and present this RCO.
