CCK checkbox or dropdown widget as a field? I am trying to setup a new CCK field for a content type to display as a checkbox but I see I don't have that option in the widgets type.
Shouldn't that be included in the default CCK?

I am using the latest CCK for Drupal 6.
The checkbox field is provided by the "Options Widget" sub-module included with CCK. From the .info file:


  Defines selection, check box and radio button widgets for text and numeric fields.


If you're not seeing checkbox as an available type you probably don't have that module enabled.
