I'm using the following code to display a tree view selection box of categories:
我正在使用以下代码显示类别的树视图选择框:
grouped_collection_select(:categories, :category_id, Category.top_level, :children, :name, :id, :name, :include_blank => true)
How can I change it to allow multiple selection?
如何更改它以允许多个选择?
Also, is it possible to have it display checkboxes instead of a select box?
此外,它是否可以显示复选框而不是选择框?

Maybe with
grouped_collection_select(:categories, :category_id, Category.top_level, :children, :name, :id, :name, :include_blank => true, { :multiple => true }
not tested!
