Question
I'm using the following code to display a tree view selection box of categories:
grouped_collection_select(:logic, :logic_id, Logic.top_level, :child, :name, :id, :name, :include_blank => true)
How can I change it to allow multiple selection?
Also, is it possible to have it display checkboxes instead of a select box?
Solution
For displaying checkbox in select box jquery multiselect i haven't tried with grouped_collection_select
but use
select/select_tag with option_groups_from_collection_for_select
it is more flexible.
