Overview

A select field that handles multiple selections

Even though it just uses a select tag helper with multiple: true, the backend is quite different from the select field. It uses the multiple_answers mixin and all of the value and default methods return arrays instead of strings.

Instance Method Details

#collect_default_values ⇒ Array

this returns field option ids based on the field default values due to funness with field options

there is a good chance this is only needed due to a bug in multiple select’s save default method We may need to take a look at this in the future. I think it could be moved to a mixin. (JH 2-28-2012)

Returns:

  • (Array) —

    An array of field option ids that correspond to the field defaults
