This won't work. I don't always want to use collection_select since I
don't always need the object/model bindings (i.e. in a search form). So
this worked for me:

<%= select_tag "some_select", "<option></option>" +
options_from_collection_for_select(@foo, "id", "item") %>

This works because options_from... returns a string of <option> tags.
Just add a blank option tag on to the front of the string.
