neoDragDropExercise creates matching, classification, and sequencing interactive activities without requiring authors to write JSON. Content is configured using standard VisualNEO Win actions, and the initial appearance is inherited from the VisualNEO style palette.

Quick Start

Insert neoDragDrop Exercise from the modern objects palette.
Note the object name, for example neoDragDropDemo.
In the page enter action, call neoDragDropExerciseClear.
Add content using actions specific to the exercise type.
Finish with neoDragDropExerciseStart.

Matching (Association)

TEXT

neoDragDropExerciseClear "neoDragDropDemo"
neoDragDropExerciseAddPair "neoDragDropDemo" "Spain" "Madrid" "" "" "Country: Spain" "10"
neoDragDropExerciseAddPair "neoDragDropDemo" "Italy" "Rome" "" "" "Country: Italy" "10"
neoDragDropExerciseStart "neoDragDropDemo"

Classification

neoDragDropExerciseAddItemToCategory "neoDragDropDemo" "Rose" "Plants" "" "" "10"
neoDragDropExerciseStart "neoDragDropDemo"

The category name used by neoDragDropExerciseAddItemToCategory must match the visible name added via neoDragDropExerciseAddCategory.

Sequencing (Ordering)

neoDragDropExerciseAddOrderItem "neoDragDropDemo" "1. Prepare materials" "" "" "10"
neoDragDropExerciseAddOrderItem "neoDragDropDemo" "2. Perform experiment" "" "" "10"
neoDragDropExerciseAddOrderItem "neoDragDropDemo" "3. Record results" "" "" "10"
