I want to use a jqgrid in a form to select one or more items from a potentially extensive list. A multiselect menu is unacceptable because of the length and the need to display a lot of information about the items to be selected. The form is re-entrant, so I need to be able to select the items that were selected the last time that the form was filled out. This is logically equivalent to specifying the selected option(s) in a select tag.
