Match interaction are those that operate in much the same way as multiple choice interaction, however the presentation is such that the student must move the items from an initial bay of selections into the proper bay locations. These interactions are the electronic kin to pen-and-paper matching questions where draw lines connecting items in a list on one side of the page to the corresponding items on the other side of the page.
A match interaction is comprised of two sets of of items (i.e., simpleAssociableChoice items)
grouped within simpleMatchSet tags. The first set defines the draggers which will begin
in a single origin bay. The second set defines the various target bays in which the
draggers can be placed. Each dragger can be moved into a target bay to create a
directedPair answer.
Starting with TN8 version 8.3, the draggers will maintain their initial order within the origin bay if they are removed from a target bay, dropped outside of the various defined bays, or returned to the origin bay.
gapMatchInteraction's in TN8 were completely revamped in the Fall of 2013, with
much-improved usability and performance in comparison to earlier implementations. In addition to
new gap styling options, you can also specify cloning rules for the gapText
choices.
Note: With this implementation of gapMatchInteraction, a target gap
may only hold up to one source dragger. You cannot override this setting.
You can specify cloning options for your source choices by adjusting the matchMax
attribute of each gapText choice. Settings for matchMax follow standard QTI conventions:
matchMax="0" — means that you can create an unlimited number of cloned choicesmatchMax="1" — indicates one choicematchMax="2" — indicates two choices| Get Responses: | [ Click Get Responses ] |

This demonstrates some cloning rules. Here are the rules for each gapText:
You may choose winter any number of times — matchMax="0"
You may choose spring twice — matchMax="2"
You may choose summer and autumn once each — matchMax="1"
Now is the of our discontent
Made glorious by this sun of York;
And all the clouds that lour'd upon our house
In the deep bosom of the ocean buried.
