Can't choose checkboxes as field widget in d7 I recall in previous versions (Or maybe even this version and mine is just bugging) you could take text or int fields and supply a list of key|values and make checkboxes or a selectbox from it.

The core module "Options" seems to offer this functionality from the module description but whenever I select field type Integer, Decimal, Float, or text the only widget option I have is a standard textbox.

Term and node references do allow checkbox widgets.

Am I seeing a bug? Is there a different way of doing this in D7? I've tried adding these field types to both node types and vocabs but neither acknowledges the existence of the checkboxes widget.
Set "Type of data to store" to List (text), List (integer) or List (float) and Check boxes will be default widget. If you can't see them, make sure List module is enabled.
