Preamble

The draggableSubsets.pl macro must be loaded.

$draggable = DraggableSubsets(
    [
        'mouse',        'ebola bacteria',
        'flu virus',    'krill',
        'house cat',    'emu',
        'coyote',       'tapir',
        'hippopotamus', 'elephant',
        'blue whale',   'eagle'
    ],
    [ [], [ 0, 4, 6, 7, 8, 9, 10 ], [ 5, 11 ], [ 1, 2, 3 ] ],
    # ['mouse','house cat','coyote','tapir','hippopatamus','elephant']
    DefaultSubsets => [
        { label => 'Animals', indices => [ 0 .. 11 ] },
        { label => 'Mammals', indices => [] },
        { label => 'Birds',   indices => [] },
        { label => 'Other',   indices => [] }
    ],
    AllowNewBuckets => 0
);

Setup

The DraggableSubsets call visually creates a set of regions called buckets that labelled boxes can be dragged between. The general form is

 $draggable = DraggableSubsets(
        $full_set,
        $answer_sets,
        %options
    );

where $full_set is the set of all labelled boxes. The $answer_sets is a nested array reference of distribution of the correct subsets. There are many options. The example here shows the use of DefaultSubsets which shows how to label and initialize the buckets. The AllowNewBuckets option allows the student in add a new bucket (1) or not (0).

See the DraggableProofs for an example of how to create drag and drop proof problems.

BEGIN_PGML
Move all animals from the "Animals" bucket into its appropriate bucket.

[_]{$draggable}
