dropSources Array

Array of id strings which determines the ListBoxes that can drag and drop their items to the current ListBox. The dropSources option describes a one way relationship. If you want a two-way connection, then set the dropSources option on both widgets.

You have to set the draggable option to all source ListBox widgets that are described in dropSources.

Example - set up a one way connection from ListBoxA to ListBoxB

<select id="listBoxA">
<select id="listBoxB">

        draggable: true

        dropSources: [ "listBoxA" ]
