given something like this:
= f.collection_select :tag_list, current_user.owned_tags(:name), :id, :name, {selected: false}, {multiple: true, "data-placeholder" => "Add tags to this document", class: 'tags-chosen-select', id: 'tag-list'}
It works fine if a tag already exists. However, What’s the best way to allow new tag adding on the fly, similar to how tagging works on work press? Is there a “Rails” way to do it?
