2290: # For examples of use see loncom/interface/lonnotify.pm
2291: #
2292: # Can be used in following order: ...

2321: # &row_closure() closes a row with a 1-pixel wide black line.
2322: #
2323: # &role_select_row() provides a select box from which to choose 1 or more roles
2324: # &course_select_row provides ways of picking groups of courses
2325: # radio buttons: all, by category or by picking from a course picker pop-up
