It does not work

[innovaweb-dev]

Thank you for your help, but the plugin does not.

jQuery 1.9.1
jQuery 1.11.4

THX,

I commented out the code.
Now it works.
Sorry for my English,

beforeStart: function beforeDragMultipleStart() {
// make sure target is selected, otherwise deselect others
// if (!(this.is('.ui-draggable') && this.is('.ui-selected'))) {
// $(".ui-draggable").removeClass('ui-selected');
// return false;
// }
}
