Currently, deselecting all values from a multiple dropdown rendered as checkboxes doesn't have any effect when submitting the form (the previous values are still there, instead of being deselected). This is because unchecked checkboxes are not sent by the browser – so the "empty selection" never gets sent. Rails `form.check_box` usually works around this by inserting an empty hidden checkbox element, that will be sent even if all others are de-selected. But the documentation warns that this is not possible when iterating over an array (rather than a model). Which is our case here. To fix this, this commit uses `collection_check_boxes` instead. It will insert the proper hidden checkboxes in all cases, and fix our use case. See https://api.rubyonrails.org/classes/ActionView/Helpers/FormOptionsHelper.html#method-i-collection_check_boxes |
