            More than one node is selectable by setting <i>selectionMode</i> to <i>multiple</i>. By default in multiple selection mode, metaKey press (e.g. <i>⌘</i>) is not necessary to add to existing selections. When the optional
            <i>metaKeySelection</i> is present, behavior is changed in a way that selecting a new node requires meta key to be present. Note that in touch enabled devices, Tree always ignores metaKey.
        </p>
        <p>In multiple selection mode, value binding should be a key-value pair where key is the node key and value is a boolean to indicate selection.</p>
