I would like to be able to put a HTML select-box in the editor view as one page template property type. The name, values, displayed texts, and single/multiple choice should be selectable for the administrator. This would be more pin-pointed to a special page type than the general category selections. It also would enable me as an administrator to make sure only one item is selected. This would be nice to have in the standard set of page properties available to administrators editing page types.
