Group your checkboxes like grouped select via “grouped_collection_select” in Rails. This gem adds a new Formtastic input type “grouped_check_boxes”, that helps you group long lists of checkboxes.

Have 3-state radiobuttons instead of a 2-state checkbox for your Boolean columns which can store NULL. This gem: 1. Provides a custom Formtastic input type `:tristate_radio` which renders 3 radios (“Yes”, “No”, “Unset”) instead of a checkbox (only where you put it). 2. Teaches Rails recognize `"null"` and `"nil"` param values as `nil` 3. Encourages you to add translations for ActiveAdmin “status tag” so that `nil` be correctly translated as “Unset” instead of “False”. Does not change controls, you need to turn it on via `as: :tristate_radio` option.

Like fromtastic only works with DataMapper and Sinatra or whatever.
