Prof-UIS features windowless built-in edit, combo, and date fields in pop-up menus if the application is customizable.
These fields have the following advantages:
- They are drag-and-droppable when the Customize dialog is open.
- The contents of these fields is automatically synchronized if there are more than one copy of a particular field.
- String values of the combo field are stored not in the control's memory but initialized each time the field is about to appear on the screen.
