I would like to display a list/menu box (multiple selections list version) that has been "selected" by the user on a previous page. (this is in an edit page, allowing the user to change his selections after seeing a confirmation page)

I know how to make a single selection list/menu display with the selected value hightlighted in the list. Is there a quick and easy (or even slow and a bit difficult) way to display all the selections in a multi-line list/menu? Or should I give up and populate a screen full of checkboxes with values from the DB? (Oh, wouldn't that be a laugh)

All help and suggestions appreciated
