I'd like to include a blank in my drop-down list using options\_from\_collection\_for\_select but cannot seem to put in the usual collection parameter `{ :include_blank => true}`. I cannot find a reference for this anywhere. Am I missing something? My statement is:

```
<%= select_tag "search", options_from_collection_for_select(TaskGroup.all.order("LOWER(task_group_name)"), "id", "task_group_name",params[:search]) %>

```

Thanking you in advance for your help,

Leah
