How to specify to FormBuilder the select tags to be generated?

I think this is a stupid question but I've double checked/searched for a clear example or explanation of how the select html tag is created for a particular field in a table, and didn't found nothing. my code goes like this $object = DB_DataObject::factory('table'); $builder =& DB_DataObject_FormBuilder::create($object); $builder->formHeaderText = "Add an Object"; $builder->submitText = "Add"; $buider-> // how to specify a field foo from table will be a SELECT ? actually my output are all input text boxes sorry but documentation in http://opensource.21st.de/16.html doesn't seem to be clear for me at this point. Should I specify there in the code? create an ini file? use an existing one? which one? Hope anybody can help me. regards My environment: Microsoft Windows XP [Version 5.1.2600] (SP1) PHP 5.0.5-dev (cli) (built: Jun 23 2005 10:28:39) Apache/2.0.52 (Win32) DB_DataObject 1.7.2 stable DB_DataObject_FormBuilder 0.17.2 beta HTML_QuickForm 3.2.4pl1 stable
