Multiple Select Helper

Selecting multiple elements in a list is sometimes tricky. You may click inadvertably on one item of the list and lost all your previous selection. You are forced to use Ctrl (or Command) clicks to select more than one element.

Multiple Select Helper allows you to create easy to use list for multiple selections from array, hashes, collections or trees. The list is build using checkboxes so you can click easily and you will not lost the elements you clicked before. As drawback you lose the use of the keyboard in the "list".

This multiple selections are very useful in many to many relationships (has_and_belongs_to_many or has_many :through with no obligatory fields) where a "add and remove" solution will be cumbersome.
