Ordered selections could be useful for multi rows and multi cells selections on tables (e.g. calendar start -> end selections).

This version of Interface Selectable plugin, let users define whether or not selections have to be ordered, simply by passing an 'ordered: true|false' value to Selectable().

By default Selectable behaves as usual.

Example:

$('#select-wrapper').Selectable( {
  accept: 'selectableitem,
  opacity: 0.2,
  selectedclass: 'selecteditem',
  helperclass: 'selecthelper',
  ordered: true,
  onselect: function(serial) {
    alert(serial.hash);
  }
});
