Make the #default_value an array of the keys of the options you want selected.
$form['item'] = array( '#type' => 'select', ... '#options' => array of all options, '#default_value' => array of keys from above options. ... );
Check http://api.drupal.org/api/file/developer/topics/forms_api_reference.html /5#default_value for more info.

Well, I'm back again, and this time I have a question about attributes for select options in a form. I have a form that has a select element (multi-select) that lists users. The form is for some admin settings for a module. When the form is displayed, I need to be able to highlight specific options in the list based on data returned from a query. I've been looking all day, and haven't been able to figure it out. There is the #attribute key, but it is for the field as whole (at least as far as I can determine), and doesn't work for each individual <option> tag.
If anybody could point me in the right direction, I would appreciate it.
Thanks.
Steve
